Hydrothermal synthesis, structure and thermal stability of diamine templated layered uranyl-vanadates
Abstract
Six new layered uranyl vanadates (NH{sub 4}){sub 2}[(UO{sub 2}){sub 2}V{sub 2}O{sub 8}] (1), (H{sub 2}EN)[(UO{sub 2}){sub 2}V{sub 2}O{sub 8}] (2), (H{sub 2}DAP)[(UO{sub 2}){sub 2}V{sub 2}O{sub 8}] (3), (H{sub 2}PIP)[(UO{sub 2}){sub 2}(VO{sub 4}){sub 2}].0,8H{sub 2}O (4), (H{sub 2}DMPIP)[(UO{sub 2}){sub 2}V{sub 2}O{sub 8}] (5), (H{sub 2}DABCO)[(UO{sub 2}){sub 2}(VO{sub 4}){sub 2}] (6) were prepared from mild-hydrothermal reactions using 1,2-ethylenediamine (EN); 1,3-diaminopropane (DAP); piperazine (PIP); 1-methylpiperazine (MPIP); 1,4-diazabicyclo[2,2,2]octane (DABCO). The structures of 1, 4, 5 and 6 were solved using single-crystal X-ray diffraction data while the structural models of 2 and 3 were established from powder X-ray diffraction data. In compounds 1, 2, 3 and 5, the uranyl-vanadate layers are built from dimers of edge-shared UO{sub 7} pentagonal bipyramids and dimers of edge-shared VO{sub 5} square pyramids further connected through edge-sharing. In 1 and 3, the layers are identical to that occurring in the carnotite group of uranyl-vanadates. In 2 and 5, the V{sub 2}O{sub 8} dimers differ in orientation leading to a new type of layer. The layers of compound 4 and 6 are built from chains of edge-shared UO{sub 7} pentagonal bipyramids connected by VO{sub 4} tetrahedra and are of uranophane-type anion topology. For the six compounds, the ammonium or organoammonium cationmore »

The utilization of the hydrothermal technique in combination with cationic organic templates has been extensively used in the synthesis of zeolites and molecular sieves. Here, the authors report the hydrothermal synthesis and single-crystal structure of (H{sub 3}N(CH{sub 2}){sub 3}NH{sub 3})[V{sub 4}O{sub 10}], a layered mixed-valence vanadium oxide with organic ammonium cations between the layers. 21 refs., 4 figs.

Hydrothermal synthesis and structure of organically templated chain, layered and framework scandium phosphates
Four scandium phosphate-based structures have been prepared hydrothermally in the presence of the primary diamines ethylenediamine and diaminobutane and the primary amine cyclohexylamine and characterised by single crystal and powder X-ray diffraction, {sup 31}P and {sup 45}Sc solid-state MAS NMR and chemical analysis. Charge balancing protons in the structures are located using bond valence sum calculations and postulated hydrogen bonding networks.

Two new fluoro-vanadyl-hydrogenarsenate compounds templated by ethylenediamine and piperazine with formula, (C{sub 2}N{sub 2}H{sub 10}){sub 0.5}[(VO)(HAsO{sub 4})F] (1) and (C{sub 4}N{sub 2}H{sub 12}){sub 0.5}[(VO)(HAsO{sub 4})F] (2), respectively, have been synthesized by using mild hydrothermal conditions under autogenous pressure. The crystal structures have been solved from single-crystal X-ray diffraction data. The phases crystallize in the P2{sub 1}/c monoclinic space group with the unit-cell parameters a=7.8634(4) A, b=7.7658(4) A, c=10.4195(6) A, {beta}=101.524(5){sup o} for compound (1) and a=6.301(1) A, b=10.244(1) A, c=10.248(1) A and {beta}=95.225(1){sup o} for compound (2). These phases exhibit a layered inorganic framework. In both cases, the structure ismore » -

The hydrothermal treatment of uranyl nitrate and 1,4-benzenebisphosphonic acid with a variety of aliphatic amines (tetramethylammonium hydroxide, tetraethylammonium hydroxide, and diethyldimethylammonium hydroxide) and small quantities of hydrofluoric acid at 200 °C results in the crystallization of a series of layered uranyl diphosphonate compounds, [(CH 3) 4N][(UO 2) 3(O 3PC 6H 4PO 3H) 2F(H 2O)]·0.5H 2O (Me 4Ubbp), [(CH 3CH 2) 4N](UO 2)[C 6H 4(PO 3H)(PO 3H 1.5)] 2(H 2O) (Et 4Ubbp), and [(CH 3CH 2) 2N(CH 3) 2][(UO 2) 3(O 3PC 6H 4PO 3H) 2F(H 2O)] (Et 2Me 2Ubbp).
