| Abstract: | Hexaamminecadmium hydrogen hexamolybdocobaltate(III) and hydrogen hexamolybdochromate(III) of compositions Cd(NH3)6] · HCoMo6O18(OH)6] · 6H2O (I) and Cd(NH3)6] · HCrMo6O18(OH)6] · 6H2O (II), respectively, were synthesized and studied by mass spectroscopy, thermo-gravimetry, X-ray powder diffraction, and IR spectroscopy. Crystals of I and II are monoclinic. For I: a = 10.79 Å, b = 3.70 Å, c = 11.95 Å, β = 91.05°, V = 470.12 Å3, ρcalc = 2.37 g/cm3, Z = 2; and for II: a = 10.80 Å, b = 3.68 Å, c = 11.97 Å, β = 91.07°, V = 468.98 Å3, ρcalc = 2.36 g/cm3, Z = 2. |
