The compound described by Cd3(PO4)2 crystallizes in the orthorhombic Cmce space group. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms. In the second Cd site, Cd(2) is bonded in a 6-coordinate geometry to one O(2), one O(4), two equivalent O(3), and two equivalent O(5) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a tetrahedral geometry to one O(1), one O(2), and two equivalent O(5) atoms. In the second P site, P(2) is bonded in a tetrahedral geometry to two equivalent O(3) and two equivalent O(4) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Cd(1) and one P(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Cd(2) and one P(1) atom. In the third O site, O(5) is bonded in a 3-coordinate geometry to two equivalent Cd(2) and one P(1) atom. In the fourth O site, O(3) is bonded in a 4-coordinate geometry to one Cd(1), two equivalent Cd(2), and one P(2) atom. In the fifth O site, O(4) is bonded in a distorted trigonal planar geometry to one Cd(1), one Cd(2), and one P(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
