The structure described by Cs2Sr2(CO3)3 crystallizes in the cubic I2_13 space group. Cs(1) is bonded in a 6-coordinate geometry to three equivalent O(1) and three equivalent O(2) atoms. Sr(1) is bonded in a 9-coordinate geometry to three equivalent O(2) and six equivalent O(1) atoms. C(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Cs(1), two equivalent Sr(1), and one C(1) atom. In the second O site, O(1) is bonded in a distorted single-bond geometry to one Cs(1), two equivalent Sr(1), and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
