| Abstract: | Hydrothermal reactions of VOSO4·3H2O, CdAc2·2H2O, NiCl2·6H2O, H3PO4, and H2O yield the first example of trimetallic phosphate materials, Ni(H2O)4]Cd(VO)(PO4)21. The single-crystal X-ray diffraction shows that its structure consists of Cd/V/O binary metal oxide lamellas decorated by PO4 tetrahedra, which are further pillared by NiO2(H2O)4 octahedra to generate a neutral 3-D framework containing two intercrossing 8-MR channels where the coordinated water molecules protrude into. Thermal and magnetic behaviors of this material were also measured. Crystal data: CdNiVP2O13H8, orthorhombic Ibca (No.73), a=7.1307(2) Å, b=18.6248(3) Å, c=14.8046(2) Å, V=1966.17(7) Å3, Z=8. |
