摘要
Hexaamminecadmium hydrogen hexamolybdocobaltate(III) and hydrogen hexamolybdochromate(III) of compositions [Cd(NH3)(6)] center dot H[CoMo6O18(OH)(6)] center dot 6H(2)O (I) and [Cd(NH3)(6)] center dot H[CrMo6O18(OH)(6)] center dot 6H(2)O (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 , b = 3.70 , c = 11.95 , beta = 91.05A degrees, V = 470.12 (3), rho(calc) = 2.37 g/cm(3), Z = 2; and for II: a = 10.80 , b = 3.68 , c = 11.97 , beta = 91.07A degrees, V = 468.98 (3), rho(calc) = 2.36 g/cm(3), Z = 2.
