The crystal structure described by CdP2 crystallizes in the tetragonal P4_32_12 space group. Cd(1) is bonded to two equivalent P(1) and two equivalent P(2) atoms to form CdP4 tetrahedra that share corners with four equivalent Cd(1)P4 tetrahedra, corners with four equivalent P(1)Cd2P2 tetrahedra, and corners with four equivalent P(2)Cd2P2 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to two equivalent Cd(1) and two equivalent P(2) atoms to form PCd2P2 tetrahedra that share corners with four equivalent Cd(1)P4 tetrahedra, corners with four equivalent P(1)Cd2P2 tetrahedra, and corners with four equivalent P(2)Cd2P2 tetrahedra. In the second P site, P(2) is bonded to two equivalent Cd(1) and two equivalent P(1) atoms to form PCd2P2 tetrahedra that share corners with four equivalent Cd(1)P4 tetrahedra, corners with four equivalent P(1)Cd2P2 tetrahedra, and corners with four equivalent P(2)Cd2P2 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
