The compound described by MgLa2(CuO2)4 crystallizes in the tetragonal I-4 space group. Mg(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. In the second La site, La(2) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. Cu(1) is bonded in a 3-coordinate geometry to one O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Mg(1), one La(1), one La(2), and one Cu(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one La(1), one La(2), and two equivalent Cu(1) atoms. is represented by the CIF card [CIF]
