biostudies-literatureUnknown64(Pt 10)Lee YHSingle crystals of Co(3)(PO(4))(2)·H(2)O, tricobalt(II) bis-[ortho-phosphate(V)] monohydrate, were obtained under hydro-thermal conditions. The compound is the second polymorph of this composition and is isotypic with its zinc analogue, Zn(3)(PO(4))(2)·H(2)O. Three independent Co(2+) cations are bridged by two independent orthophosphate anions. Two of the metal cations exhibit a distorted tetra-hedral coordination while the third exhibits a considerably distorted [5 + 1] octa-hedral coordination environment with one very long Co-O distance of 2.416 (3) Å. The former cations are bonded to four different phosphate anions, and the latter cation is bonded to four anions (one of which is bidentate) and one water mol-ecule, leading to a framework structure.
