The crystal structure described by Sr(CO2)3 crystallizes in the monoclinic P2_1/c space group. Sr(1) is bonded in a 9-coordinate geometry to one O(3), two equivalent O(1), two equivalent O(2), two equivalent O(4), and two equivalent O(5) atoms. There are three inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 150 degrees geometry to one O(3) and one O(4) atom. In the second C site, C(2) is bonded in a bent 150 degrees geometry to one O(1) and one O(6) atom. In the third C site, C(3) is bonded in a distorted bent 120 degrees geometry to one O(2) and one O(5) atom. There are six inequivalent O sites. In the first O site, O(5) is bonded in a distorted single-bond geometry to two equivalent Sr(1) and one C(3) atom. In the second O site, O(6) is bonded in a single-bond geometry to one C(2) atom. In the third O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Sr(1) and one C(2) atom. In the fourth O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Sr(1) and one C(3) atom. In the fifth O site, O(3) is bonded in a distorted single-bond geometry to one Sr(1) and one C(1) atom. In the sixth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent Sr(1) and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
