The structure described by Mg(Co3P2)2 crystallizes in the orthorhombic Amm2 space group. Mg(1) is bonded to two equivalent Co(3) and two equivalent P(2) atoms to form distorted corner-sharing MgCo2P2 tetrahedra. There are four inequivalent Co sites. In the first Co site, Co(1) is bonded in a 4-coordinate geometry to one P(1), one P(2), and two equivalent P(3) atoms. In the second Co site, Co(2) is bonded in a 5-coordinate geometry to one P(2), two equivalent P(1), and two equivalent P(3) atoms. In the third Co site, Co(3) is bonded to one Mg(1), one P(3), and two equivalent P(1) atoms to form distorted corner-sharing CoMgP3 trigonal pyramids. In the fourth Co site, Co(4) is bonded in a 5-coordinate geometry to one P(3) and four equivalent P(1) atoms. There are three inequivalent P sites. In the first P site, P(1) is bonded in a 6-coordinate geometry to one Co(1), one Co(2), two equivalent Co(3), and two equivalent Co(4) atoms. In the second P site, P(2) is bonded in a 5-coordinate geometry to two equivalent Mg(1), one Co(2), and two equivalent Co(1) atoms. In the third P site, P(3) is bonded in a 9-coordinate geometry to one Co(4), two equivalent Co(2), two equivalent Co(3), and four equivalent Co(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
