Description
Summary:The title compound, Cd2P4O12, dicadmium cyclo-tetraphosphate, crystallizes isotypically with the members of the series MII2P4O12, where M = Mg, Mn, Fe, Co, Ni or Cu. Two CdO6 octahedra, one with 2 and one with overline{1} symmetry, share corners with the centrosymmetric P4O124− ring anion that is built up from four corner-sharing PO4 tetrahedra. The isolated ring anions are arranged in layers parallel to (10overline{1}) with the CdO6 octahedra situated between these layers. The main difference between the individual MII2P4O12 structures pertains to the different sizes of the MO6 octahedra whereas the geometric parameters of all cyclo-P4O124− anions are very similar.
