| Abstract: | Sodium hexamolybdocobaltate(III) Na3CoMo6O18(OH)6] · 8H2O (I) and sodium hexamolybdochromate Na3CrMo6O18(OH)6] · 8H2O (II) were synthesized and studied by mass spectrometry, thermogravimetry, powder X-ray diffraction, and IR spectroscopy. The crystals are monoclinic. For compound a = 10.31 Å, b = 10.31 Å, c = 17.55 Å, β = 100.93°, V = 1834.77 Å3, ρcalcd = 3.04 g/cm3, Z = 3; for compound II: a = 10.33 Å, b = 10.33 Å, c = 17.59 Å, β = 100.98°, V = 1835.09 Å3, ρcalcd = 3.01 g/cm3, Z = 3. |
