The compound described by MgCrGaO4 crystallizes in the monoclinic Pm space group. Mg(1) is bonded in a 4-coordinate geometry to one O(1), one O(3), and two equivalent O(4) atoms. Cr(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form edge-sharing CrO6 octahedra. Ga(1) is bonded in a 5-coordinate geometry to one O(2), two equivalent O(1), and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to one Mg(1), one Cr(1), and two equivalent Ga(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Cr(1) and one Ga(1) atom. In the third O site, O(3) is bonded in a rectangular see-saw-like geometry to one Mg(1), one Cr(1), and two equivalent Ga(1) atoms. In the fourth O site, O(4) is bonded in a rectangular see-saw-like geometry to two equivalent Mg(1) and two equivalent Cr(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
