The material structure described by Cd3P2 crystallizes in the tetragonal P4_2/nmc space group. There are three inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 4-coordinate geometry to one P(1), one P(2), and two equivalent P(3) atoms. In the second Cd site, Cd(2) is bonded to one P(1), one P(2), and two equivalent P(3) atoms to form distorted corner-sharing CdP4 tetrahedra. In the third Cd site, Cd(3) is bonded in a 4-coordinate geometry to one P(1), one P(2), and two equivalent P(3) atoms. There are three inequivalent P sites. In the first P site, P(3) is bonded in a 6-coordinate geometry to two equivalent Cd(1), two equivalent Cd(2), and two equivalent Cd(3) atoms. In the second P site, P(1) is bonded in a 6-coordinate geometry to two equivalent Cd(1), two equivalent Cd(2), and two equivalent Cd(3) atoms. In the third P site, P(2) is bonded in a 6-coordinate geometry to two equivalent Cd(1), two equivalent Cd(2), and two equivalent Cd(3) atoms. is represented by the CIF file [CIF]
