The crystal structure described by Mg(C2O3)2 crystallizes in the monoclinic C2/c space group. Mg(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a linear geometry to one C(1) and one C(2) atom. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one C(1), one O(1), and one O(2) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Mg(1) and one C(2) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Mg(1) and one C(2) atom. In the third O site, O(3) is bonded in a single-bond geometry to one Mg(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
