The structure described by SrMgCrO3 crystallizes in the monoclinic Cm space group. Sr(1) is bonded in a 5-coordinate geometry to one O(2) and four equivalent O(1) atoms. Mg(1) is bonded in a trigonal non-coplanar geometry to one O(2) and two equivalent O(1) atoms. Cr(1) is bonded in a rectangular see-saw-like geometry to two equivalent 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 two equivalent Sr(1), one Mg(1), and one Cr(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Sr(1), one Mg(1), and two equivalent Cr(1) atoms. is represented by the CIF file [CIF]
