Title: Comparative high-pressure study and chemical bonding analysis of Rh{sub 3}Bi{sub 14} and isostructural Rh{sub 3}Bi{sub 12}Br{sub 2}

Abstract

The binary compound Rh{sub 3}Bi{sub 14} was synthesized from the elements. The compound is isostructural with Rh{sub 3}Bi{sub 12}Br{sub 2}, crystallizes with the orthorhombic space group Fddd (no. 70) and lattice parameters a=6.8959(15) A, b=17.379(3) A, c=31.758(6) A. The crystal structure consists of a three-dimensional (3D) framework of edge-sharing cubes and square antiprisms (RhBi{sub 8/2}). It is closely related to the intermetallic compound RhBi{sub 4}, in which two Y-like frameworks of antiprisms interpenetrate. In Rh{sub 3}Bi{sub 14} and Rh{sub 3}Bi{sub 12}Br{sub 2}, additional bismuth and bromine anions, respectively, fill the channels of the 3D polyhedral framework formed by covalently bonded rhodium and bismuth atoms. High-pressure X-ray powder diffraction data from synchrotron measurements of Rh{sub 3}Bi{sub 14} and Rh{sub 3}Bi{sub 12}Br{sub 2} indicate a high stability of both compounds in the investigated range from ambient pressure to ca. 30 GPa at ambient temperature. - Graphical abstract: Rh{sub 3}Bi{sub 14} isostructural with Rh{sub 3}Bi{sub 12}Br{sub 2} consists of a 3D framework of edge-sharing cubes and square antiprisms.

  • A new phase, Bi{sub 13}Mo{sub 4}VO{sub 34}E{sub 13} (E:Bi(III) lone pair) was found in the Bi{sub 2}O{sub 3}-MoO{sub 3}-V{sub 2}O{sub 5} system and its formula determined via single crystal analysis and confirmed by solid state synthesis. It crystallizes in the monoclinic system, space group P2/c, with cell parameters a = 11.652(7){angstrom}, b = 5.7923(8) {angstrom}, c = 24.420(9){angstrom}, {beta} = 101.38(6){degrees}, and Z = 2. The crystal structure is built up by infinite [Bi{sub 12}O{sub 14}E{sub 12}]{sub n} columns surrounded by 10 (Mo, V)O{sub 4} tetrahedra, situated on layers parallel to (100) and (001), with an extra Bi atom locatedmore » at the intersection of these {open_quotes}(Mo, V)O{sub 4} layers{close_quotes} in between two tetrahedra.Taking into account the cell dimensions and structural details of Bi{sub 13}Mo{sub 4}VO{sub 34}E{sub 13} which show that a reported phase like Bi{sub 6}Mo{sub 2}O{sub 15} could also be isostructural, a new hypothesis based on the possible replacement of BiO{sub 4} trigonal bipyramid and/or BiO{sub 3}E tetrahedra for MoO{sub 4} tetrahedra strengthens the probability that there is a continuous solid solution in the Bi{sub 2}O{sub 3}-MoO{sub 3} system between the compositions 1.43 Bi{sub 2}O{sub 3}: 1 MoO{sub 3} and 1.75 Bi{sub 2}O{sub 3}: 1 MoO{sub 3}. Synthesis and cell dimensions of various compositions supporting these ideas are given. The domain of existence for such phases can extend in the pseudo-ternary Bi{sub 2}O{sub 3}-MoO{sub 3}-V{sub 2}O{sub 5} system up to the phase Bi{sub 13}Mo{sub 4}VO{sub 34}; this triangular area excludes Bi{sub 26}Mo{sub 10}O{sub 69} and Bi{sub 26}Mo{sub 6}V{sub 4}O{sub 67} compositions.« less
  • Hydrothermal reactions of molybdenum-oxide precursors with polyalcohols in the presence of base yielded two series of mixed-valence oxomolybdenum clusters, the hexadecanuclear species [XH{sub 12}(Mo{sup VI}O{sub 3}){sub 4}Mo{sup V}{sub 12}O{sub 40}]{sup m{minus}}(X=Na{sup +}, m=7; X=2H{sup +}, m=6) and the superclusters [XH{sub n}Mo{sup VI}{sub 6}Mo{sup V}{sub 36}O{sub 109}(OCH{sub 2}){sub 3}CR{sub 7}]{sup m{minus}} (X=Na-(H{sub 2}O){sub 3}{sup +}, m=9, n=13; X=Na(H{sub 2}O){sub 3}{sup +}, m=7, n=15; X=MoO{sub 3}, m=9, n=14; X=MoO{sub 3}, m=10, n=13). In a representative synthesis for the hexadencanuclear class of materials, the hydrothermal reaction of a mixture of Na{sub 2}MoO{sub 4}{center_dot}2H{sub 2}O, MoO{sub 3}, Mo metal, and NH{sub 4}Cl produced (NH{submore » 4}){sub 7}[NaMo{sub 16}(OH){sub 12}O{sub 40}]{center_dot}4h{sub 2}O (1{center_dot}4H{sub 2}O) as red-orange crystals. The compound (Me{sub 3}NH){sub 4}K{sub 2}[H{sub 2}Mo{sub 16}(OH){sub 40}]{center_dot}8H{sub 2}O(2{center_dot}8H{sub 2}O(2{center_dot}8H{sub 2}O) was prepared in a similar fashion. The structure of the anion of 1 consists of an {epsilon}-Keggin core H{sub 12}Mo{sub 12}O{sub 40}, capped on four hexagonal faces by MoO{sub 3} units and encapsulating a Na{sup +} cation. The structure of the oxomolybdenum framework of 2 is essentially identical to that of 1; however, the central cavity is now occupied by 2H{sup +}.« less
  • Intermetallic materials with large unit cells are scientifically interesting and challenging due to their structural and chemical complexity. The investigated hexagonal Mg{sub 2}Co{sub 3}Sn{sub 10+x} crystallizes with 120 atoms per unit cell and a unit cell volume of 2655 A{sup 3}. An in-house single-crystal high pressure study was done using a recently developed low background diamond-anvil cell. The investigated compound is structurally stable up to the highest reached pressure of 9.69 GPa. Compressibility measurements revealed the c{sup {yields}}-axis to be slightly less compressible than the a{sup {yields}}-axis. A chemical bonding analysis based on the analysis of the topology of themore » electron localization function identified Mg{sub 2}Co{sub 3}Sn{sub 10+x} as a compound combining localized and delocalized chemical bonding in its structure. The macroscopic properties of the compound are dominated by the metallic 3D framework, which is also responsible for the anisotropic compressibility. - Mg{sub 2}Co{sub 3}Sn{sub 10+x} belongs to the fascinating group of compounds combining localized and delocalized chemical bonding of the same element type in their structure. The structural stability up to 9.69 GPa and chemical bonding of this complex metallic alloy (120 atoms per unit cell) is reported.« less
  • The magnetic molecular cluster [Fe{sub 8}(N{sub 3}C{sub 6}H{sub 15}){sub 6}O{sub 2}(OH){sub 12}]{sup 8+}[Br{sub 8}{center_dot}9H{sub 2}O]{sup 8-}, in short Fe8, has been investigated at low temperature by {sup 1}H-NMR and relaxation measurements. Some measurements of {sup 2}D-NMR in partially deuterated Fe8 clusters will also be reported. Upon decreasing temperature the NMR spectra display a very broad and structured signal which is the result of the internal local fields at the proton sites due to the local moments of the Fe(III) ions in the total S=10 magnetic ground state. The proton and deuteron NMR spectra have been analyzed and the different resonancemore » peaks have been attributed to the different proton groups in the molecule. The simulation of the spectra by using a dipolar hyperfine field and the accepted model for the orientation of the Fe(III) local moments do not agree with the experiments even when the magnitude of the local Fe(III) moments is allowed to vary. It is concluded that a positive contact hyperfine interaction of the same order of magnitude as the dipolar interaction is present for all proton sites except the water molecules. The temperature and magnetic field dependence of the nuclear spin-lattice relaxation rate is ascribed to the fluctuations of the local Fe(III) moments, which follow rigidly the fluctuations of the total ground state magnetization of the nanomagnet. By using a simple model already utilized for the Mn12 cluster, we derive the value of the spin phonon coupling constant which determines the lifetime broadening of the different magnetic quantum number m substates of the S=10 ground state. It is shown that the lifetime broadening decreases rapidly on lowering the temperature. When the lifetime becomes longer than the reciprocal of the frequency shift of the proton lines a structure emerges in the NMR spectrum reflecting the ''frozen'' local moment configuration.« less
  • The new compounds NaBi{sub 6}O{sub 9}X (X = Br, I) were synthesized. Attempts to synthesize the analogous RbBi{sub 6}O{sub 9}X (X = Br, I) compounds yielded mixed systems with about 10% of the Rb atoms replaced by Na and K atoms. Another mixed system, Na{sub 0.77(3)}K{sub 0.23(3)}Bi{sub 6}O{sub 9}I, was obtained incidentally. The corresponding ABi{sub 6}O{sub 9}X compounds with X = Cl or A = Cs could not be obtained. The influence of A and X on the size of the ABi{sub 6}O{sub 9}X unit cell is discussed.
