| 摘 要： | A novel heteropoly compound, containing two kinds of coordinated cations, K(H2O)2Ni(H2O)6]2V10O28], has been synthesized through routine process and characterized by elemental analyses, IR, 51V NMR and single crystal X-ray diffraction. It crystallizes in the triclinic system, space group P1 with a=0.87382(17) nm, b=1.075 4(2) nm, c=1.111 1(2) nm, α=65.10(3)°, β=75.01(3)°, γ=70.63(3)°, V=0.884 8(3) nm3 and Z=1. The X-ray analysis reveals that the two kinds of coordinated cations are linked by three shared coordinated water molecules, and K+ cations coordinate with ten oxygen atoms: five of which come from V10O286- anion, the other five from water molecules. The title compound exhibits extended 2D array building up of V10O286- groups connected by ten-coordinated K+ cations. The hexahydrated nickel cations Ni(H2O)62+ lie in neat apposition to three adjacent V10O286- clusters. CSD: 413271.

| Abstract: | A novel heteropoly compound, containing two kinds of coordinated cations, K(H2O)2Ni(H2O)6]2V10O28], has been synthesized through routine process and characterized by elemental analyses, IR, 51V NMR and single crystal X-ray diffraction. It crystallizes in the triclinic system, space group P1 with a=0.873 82(17) nm, b=1.075 4(2)nm, c=1.111 1(2) nm, α=65.10(3)°, β=75.01(3)°, γ=70.63(3)°, V=0.884 8(3) nm3 and Z=1. The X-ray analysis reveals that the two kinds of coordinated cations are linked by three shared coordinated water molecules, and K+cations coordinate with ten oxygen atoms: five of which come from V10O6-28 anion, the other five from water molecules. The title compound exhibits extended 2D array building up of V10O6-28 groups connected by tencoordinated K+ cations. The hexahydrated nickel cations Ni(H2O)62+ lie in neat apposition to three adjacent V10O286-clusters. CSD: 413271. |
