Title: An open-framework three-dimensional indium oxalate: [In(OH)(C{sub 2}O{sub 4})(H{sub 2}O)]{sub 3}.H{sub 2}O

Abstract

By hydrothermal reaction of In{sub 2}O{sub 3} with H{sub 2}C{sub 2}O{sub 4}.2H{sub 2}O in the presence of H{sub 3}BO{sub 3} at 155 deg. C, an open-framework three-dimensional indium oxalate of formula [In(OH)(C{sub 2}O{sub 4})(H{sub 2}O)]{sub 3}.H{sub 2}O (1) has been obtained. The compound crystallizes in the trigonal system, space group R3c with a=18.668(3)A, c=7.953(2)A, V=2400.3(7)A{sup 3}, Z=6, R{sub 1}=0.0352 at 298K. The small pores in 1 are filled with water molecules. It loses its filled water at about 180 deg. C without the change of structure, then the bounded water at 260 deg. C, and completely decompounds at 324 deg. C. The residue is confirmed to be In{sub 2}O{sub 3}.

The structure consists of neutral manganese phosphite layers, [Mn(HPO{sub 3})]{sub i}nfinity, formed by MnO{sub 6} octahedra and HPO{sub 3} units, cross-linked by the oxalate moieties. The organic cations occupy the middle of the 8-membered one-dimensional channels. Magnetic studies indicate weak antiferromagnetic interactions between the Mn{sup 2+} ions. - Abstract: A new antiferromagnetic three-dimensional inorganic-organic hybrid compound, [C{sub 2}N{sub 2}H{sub 10}][Mn{sub 2}{sup II}(OH{sub 2}){sub 2}(HPO{sub 3}){sub 2}(C{sub 2}O{sub 4})] has been prepared hydrothermally.more » The compound has neutral manganese layers pillared by oxalate units.

  • Two modifications of the new uranyl oxalate hydroxide dihydrate [UO{sub 2}){sub 2}(C{sub 2}O{sub 4})(OH){sub 2}(H{sub 2}O){sub 2}] (1 and 2) and one form of the new uranyl oxalate hydroxide trihydrate [(UO{sub 2}){sub 2}(C{sub 2}O{sub 4})(OH){sub 2}(H{sub 2}O){sub 2}].H{sub 2}O (3) were synthesized by hydrothermal methods and their structures determined from single-crystal X-ray diffraction data. The crystal structures were refined by full-matrix least-squares methods to agreement indices R(wR)=0.0372(0.0842) and 0.0267(0.0671) calculated for 1096 and 1167 unique observed reflections (I>2{sigma}(I)), for {alpha} (1) and {beta} (2) forms, respectively and to R(wR)=0.0301(0.0737) calculated for 2471 unique observed reflections (I>2{sigma}(I)), for 3. The {alpha}-formmore » of the dihydrate is triclinic, space group P1-bar , Z=1, a=6.097(2), b=5.548(2), c=7.806(3)A, {alpha}=89.353(5), {beta}=94.387(5), {gamma}=97.646(5){sup o}, V=260.88(15)A{sup 3}, {beta}-form is monoclinic, space group C2/c, Z=4, a=12.180(3), b=8.223(2), c=10.777(3)A, {beta}=95.817(4), V=1073.8(5)A{sup 3}. The trihydrate is monoclinic, space group P2{sub 1}/c, Z=4, a=5.5095(12), b=15.195(3), c=13.398(3)A, {beta}=93.927(3), V=1119.0(4)A{sup 3}. In the three structures, the coordination of uranium atom is a pentagonal bipyramid composed of dioxo UO{sub 2}{sup 2+} cation perpendicular to five equatorial oxygen atoms belonging to one bidentate oxalate ion, one water molecule and two hydroxyl ions in trans configuration in 2 and in cis configuration in 1 and 3. The UO{sub 7} polyhedra are linked through hydroxyl oxygen atoms to form different structural building units, dimers [U{sub 2}O{sub 10}] obtained by edge-sharing in 1, chains [UO{sub 6}]{sub {approx}} and tetramers [U{sub 4}O{sub 26}] built by corner-sharing in 2 and 3, respectively. These units are further connected by oxalate entities that act as bis-bidentate to form one-dimensional chains in 1 and bi-dimensional network in 2 and 3. These chains or layers are connected in frameworks by hydrogen-bond arrays.« less
