Bottom Line: Two CdO(6) octa-hedra, one with 2 and one with symmetry, share corners with the centrosymmetric P(4)O(12) (4-) ring anion that is built up from four corner-sharing PO(4) tetra-hedra.The isolated ring anions are arranged in layers parallel to (10) with the CdO(6) octa-hedra situated between these layers.The main difference between the individual M(II) (2)P(4)O(12) structures pertains to the different sizes of the MO(6) octa-hedra whereas the geometric parameters of all cyclo-P(4)O(12) (4-) anions are very similar.

ABSTRACT
The title compound, Cd(2)P(4)O(12), dicadmium cyclo-tetra-phosphate, crystallizes isotypically with the members of the series M(II) (2)P(4)O(12), where M = Mg, Mn, Fe, Co, Ni or Cu. Two CdO(6) octa-hedra, one with 2 and one with symmetry, share corners with the centrosymmetric P(4)O(12) (4-) ring anion that is built up from four corner-sharing PO(4) tetra-hedra. The isolated ring anions are arranged in layers parallel to (10) with the CdO(6) octa-hedra situated between these layers. The main difference between the individual M(II) (2)P(4)O(12) structures pertains to the different sizes of the MO(6) octa-hedra whereas the geometric parameters of all cyclo-P(4)O(12) (4-) anions are very similar.
