The material described by MgLa3Cu4(P2O)2 crystallizes in the orthorhombic Immm space group. Mg(1) is bonded to two equivalent La(1), two equivalent Cu(1), and four equivalent P(2) atoms to form a mixture of corner and edge-sharing MgLa2Cu2P4 hexagonal bipyramids. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 8-coordinate geometry to two equivalent Mg(1), four equivalent Cu(2), and two equivalent P(1) atoms. In the second La site, La(2) is bonded in a 4-coordinate geometry to two equivalent Cu(1) and four equivalent O(1) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 7-coordinate geometry to one Mg(1), two equivalent La(2), two equivalent P(1), and two equivalent P(2) atoms. In the second Cu site, Cu(2) is bonded in a 6-coordinate geometry to two equivalent La(1), two equivalent P(1), and two equivalent P(2) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 4-coordinate geometry to one La(1), two equivalent Cu(1), and two equivalent Cu(2) atoms. In the second P site, P(2) is bonded in a 6-coordinate geometry to two equivalent Mg(1), two equivalent Cu(1), and two equivalent Cu(2) atoms. O(1) is bonded in a 4-coordinate geometry to four equivalent La(2) atoms. is represented by the CIF file [CIF]
