The crystal structure described by BaMgCu3O4 crystallizes in the monoclinic P2/m space group. Ba(1) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. Mg(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a linear geometry to two equivalent O(2) atoms. In the second Cu site, Cu(2) is bonded in a linear geometry to one O(1) and one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to two equivalent Ba(1), two equivalent Mg(1), and one Cu(2) atom. In the second O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Ba(1), one Cu(1), and one Cu(2) atom. is represented by the CIF file [CIF]
