The compound described by Mg(Rh3P2)2 crystallizes in the hexagonal P-6m2 space group. Mg(1) is bonded to six equivalent Rh(1) and six equivalent P(1) atoms to form face-sharing MgP6Rh6 cuboctahedra. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 6-coordinate geometry to two equivalent Mg(1), two equivalent P(1), and two equivalent P(2) atoms. In the second Rh site, Rh(2) is bonded in a 5-coordinate geometry to one P(2) and four equivalent P(1) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 8-coordinate geometry to two equivalent Mg(1), two equivalent Rh(1), and four equivalent Rh(2) atoms. In the second P site, P(2) is bonded in a 9-coordinate geometry to three equivalent Rh(2) and six equivalent Rh(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
