The material structure described by Cs(SeO3)3 crystallizes in the monoclinic P2_1/c space group. Cs(1) is bonded in a 10-coordinate geometry to one O(4), one O(6), one O(7), one O(9), two equivalent O(3), two equivalent O(5), and two equivalent O(8) atoms. There are three 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 distorted tetrahedral geometry to one O(1), one O(4), one O(5), and one O(6) atom. In the third Se site, Se(3) is bonded in a tetrahedral geometry to one O(2), one O(7), one O(8), and one O(9) atom. There are nine inequivalent O sites. In the first O site, O(5) is bonded in a distorted single-bond geometry to two equivalent Cs(1) and one Se(2) atom. In the second O site, O(6) is bonded in a single-bond geometry to one Cs(1) and one Se(2) atom. In the third O site, O(7) is bonded in a distorted single-bond geometry to one Cs(1) and one Se(3) atom. In the fourth O site, O(8) is bonded in a single-bond geometry to two equivalent Cs(1) and one Se(3) atom. In the fifth O site, O(1) is bonded in a bent 150 degrees geometry to one Se(1) and one Se(2) atom. In the sixth O site, O(9) is bonded in a single-bond geometry to one Cs(1) and one Se(3) atom. In the seventh O site, O(2) is bonded in a bent 120 degrees geometry to one Se(1) and one Se(3) atom. In the eighth O site, O(3) is bonded in a single-bond geometry to two equivalent Cs(1) and one Se(1) atom. In the ninth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Cs(1) and one Se(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
