| Abstract: | Tetramminenickel hydrogen hexamolybdoaluminate and hexamolybdogallate(III) of compositions Ni(NH3)4] · HAlMo6O18(OH)6] · 10H2O (I) and Ni(NH3)4] · HGaMo6O18(OH)6] · 10H2O (II) were synthesized and characterized by mass spectrometry, thermogravimetry, X-ray powder diffraction, and IR spectroscopy. Their crystals are triclinic. For compound I, a= 17.30 Å, b= 14.69 Å, c= 10.45 Å, α = 129.07, β = 65.91°, γ = 138.01°, V = 1338.7l Å3, ρcalcd = 2.75g/cm3, Z = 2; for compound II, a = 17.38 Å, b= 14.75 Å, c= 10.51 Å, α = 131.38°, β= 65.96°, γ = 138.09, V = 1338.15 Å3, ρcalcd = 2.68 g/cm3, Z = 2. |
