摘要:
The three-dimensional vanadium-nickel phosphate (C2H10N2)4[H2Ni(H2O)2(VO)8(OH)4(PO4)8]center dot H2O (1) was prepared by hydrothermal methods and its structure and electrochemical properties were characterized. The compound crystallizes in the monoclinic system with the space group P21/n and cell parameters a = 14.392(3) angstrom, b = 10.122(2) angstrom, c = 18.305(4) angstrom, = 90.34(3)degrees, V = 2666.7(9) angstrom 3, Z = 2. The structure consists of macroanionic VNiP layers constructed from VO5 square pyramids, NiO6 octahedra, and PO43 tetrahedral groups. The layers are further connected into a 3D infinite structure through the NiO6 octahedra and there are organic species protonated ethanediamine molecules and water molecules located, which make the structure more stable. Its electron sponge behavior was revealed via electrochemical tests.
