The material described by MgMn4(CuO4)2 crystallizes in the monoclinic Cm space group. Mg(1) is bonded in a 4-coordinate geometry to one O(5), one O(6), and two equivalent O(4) atoms. There are three inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 5-coordinate geometry to one O(2), two equivalent O(1), and two equivalent O(4) atoms. In the second Mn site, Mn(2) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(3), one O(5), and one O(6) atom. In the third Mn site, Mn(3) is bonded in a 5-coordinate geometry to one O(3), two equivalent O(1), and two equivalent O(4) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a linear geometry to two equivalent O(4) atoms. In the second Cu site, Cu(2) is bonded in a linear geometry to two equivalent O(1) atoms. There are six inequivalent O sites. In the first O site, O(1) is bonded to one Mn(1), one Mn(2), one Mn(3), and one Cu(2) atom to form a mixture of distorted edge and corner-sharing OMn3Cu trigonal pyramids. In the second O site, O(2) is bonded in a trigonal non-coplanar geometry to one Mn(1) and two equivalent Mn(2) atoms. In the third O site, O(3) is bonded in a trigonal non-coplanar geometry to one Mn(3) and two equivalent Mn(2) atoms. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Mg(1), one Mn(1), one Mn(3), and one Cu(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to one Mg(1) and two equivalent Mn(2) atoms. In the sixth O site, O(6) is bonded in a distorted trigonal planar geometry to one Mg(1) and two equivalent Mn(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
