The compound described by SrC2O5 crystallizes in the monoclinic C2/m space group. Sr(1) is bonded in a 8-coordinate geometry to one O(3), one O(4), two equivalent O(2), and four equivalent O(1) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to two equivalent O(1) atoms. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one O(2) and one O(3) 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 3-coordinate geometry to two equivalent Sr(1) and one C(2) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Sr(1) and one C(2) atom. In the fourth O site, O(4) is bonded in a single-bond geometry to one Sr(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
