The structure described by Cs(SeO3)2 crystallizes in the triclinic P-1 space group. Cs(1) is bonded in a 10-coordinate geometry to one O(4), one O(5), one O(6), two equivalent O(2), two equivalent O(3), and three equivalent O(1) atoms. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a trigonal non-coplanar geometry to one O(1), one O(2), and one O(3) atom. In the second Se site, Se(2) is bonded in a trigonal non-coplanar geometry to one O(4), one O(5), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent Cs(1) and one Se(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Cs(1) and one Se(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Cs(1) and one Se(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Cs(1) and one Se(2) atom. In the fifth O site, O(5) is bonded in a distorted single-bond geometry to one Cs(1) and one Se(2) atom. In the sixth O site, O(6) is bonded in a single-bond geometry to one Cs(1) and one Se(2) atom. is represented by the CIF file [CIF]
