Abstract
In the structure of the title compound, [Co4(C2O4)(PO4)2(H2O)2]n, there are layers composed of the phosphate anions and two independent CoII cations. These layers are parallel to (001) and are bridged by the oxalate anions that are situated in special positions on centres of symmetry. One independent Co atom has an octahedral coordination, while the second independent Co atom is coordinated in a trigonal–bipyramidal coordination that includes the water molecule. The crystal packing is stabilized by O—H⋯O hydrogen bonds between the coordinated water molecules and oxalate O atoms.
