Ammonium decamolybdodimetallates (NH4)n[M2Mo10O34(OH)4] · 7H2O, where M = Cr3+ (n = 6), Cu2+ (n = 8), or Ni2+ (n = 8), were synthesized for the first time and studied by X-ray diffraction, thermogravimetry, and IR spectroscopy. The compounds crystallize in the triclinic system with the following unit cell parameters: a = 10.68(2) Å, b = 9.46(2) Å, c = 7.97(2) Å, α = 75.12(3)°, β = 96.82(3)°, γ = 102.21(3)°, V = 754.4(3) Å3, ρcalcd = 4.05 g/cm3, Z = 1 for the chromium compound; and a = 10.57(2) Å, b = 9.29(2) Å, c = 8.47(2) Å, α = 73.91(3)°, β = 96.05(3)°, γ = 104.71(3)°, V = 854.3(3) Å3, ρcalcd = 3.68 g/cm3, Z = 1 (for the copper compound); and a = 10.96(2) Å, b = 8.95(2) Å, c = 7.40(2) Å, α = 71.76(3)°, β = 97.04(3)°, γ = 102.91(3)°, V = 875.3(3)Å3, ρcalcd = 3.65 g/cm3, Z = 1 for the nickel compound. 相似文献

Acid pyridine-3-carboxylic acid dodecatungstenphosphate (C6NO2H5)2H[PW12O40]·2H2O is synthesized. The compound is studied by chemical analysis, IR spectroscopy, X-ray crystallography, and thermogravimetry. The compound is found to crystallize at 290 K in a hexagonal crystal system (space group \(R\bar 3\) ) (I) with the unit cell parameters: a = 33.015(6) Å, c = 12.010(2) Å, γ = 120°, V = 11337(4) Å3, Z = 9. When the temperature decreases to 100 K, a phase transition is observed leading to an increase in symmetry to \(R\bar 3m\) (II), with the unit cell parameters: a = 33.072(1) Å, c = 24.234(1) Å, γ = 120°, V = 22955(2) Å3, Z = 18. 相似文献
