inorganic compounds
Purple crystals of the title compound, cobalt dizinc phosphate tetrahydrate, have been prepared hydrothermally. It is isostructural with hopeite, Zn3(PO4)2·4H2O, with cobalt completely substituted for zinc at the octahedral site, resulting in [ZnPO4]− layers bridged by cis Co(H2O)4O2 octahedra. Various O—HO hydrogen bonds help to stabilize the structure. The Co atom and two water O atoms occupy special positions with mirror symmetry,

Green crystals of the title compound, nickel dizinc phosphate tetrahydrate, have been prepared hydrothermally. The compound is isostructural with hopeite, Zn3(PO4)2·4H2O, with nickel completely substituted for zinc at the octahedral site, resulting in [ZnPO4]− layers bridged by cis Ni(H2O)4O2 octahedra. O—HO hydrogen bonds help to stabilize the structure. The Ni atom and two water O atoms occupy special positions with mirror symmetry.
