| Abstract: | [Co(NH3)6] · H2[NiMo6O18(OH)6] · 6H2O (I) and [Co(NH3)6] · H2[ZnMo6O18(OH)6] · 6H2O (II) have been synthesized and studied by mass spectroscopy, thermogravimetry, and X-ray powder diffraction. The crystals of compounds I and II are monoclinic, Z = 1; for compound I: a = 16.10 Å, b = 5.58 Å, c = 12.22 Å, β = 117.86°, V = 1045.14 Å3, and ρcalcd = 2.26 g/cm3; for compound II: a = 16.12 Å, b = 5.52 Å, c = 12.12 Å, β = 117.90°, V = 1043.21 Å3, and ρcalcd = 2.21 g/cm3. |
