SrC2O4 crystallizes in the orthorhombic P2_12_12_1 space group. Sr(1) is bonded in a 6-coordinate geometry to one O(2), one O(3), two equivalent O(1), and two equivalent O(4) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one O(3) and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Sr(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Sr(1) and one C(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Sr(1) and one C(2) atom. In the fourth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Sr(1) and one C(2) atom.
