The compound described by Ba(SeO3)2 crystallizes in the triclinic P-1 space group. Ba(1) is bonded in a 10-coordinate geometry to one O(1), one O(3), one O(6), two equivalent O(2), two equivalent O(4), and three equivalent O(5) atoms. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a water-like geometry to one O(5) and one O(6) atom. In the second Se site, Se(2) is bonded in a single-bond geometry to one O(3) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Ba(1) and one O(2) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Ba(1) and one O(1) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to one Ba(1), one Se(2), and one O(4) atom. In the fourth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Ba(1) and one O(3) atom. In the fifth O site, O(5) is bonded in a 1-coordinate geometry to three equivalent Ba(1) and one Se(1) atom. In the sixth O site, O(6) is bonded in a distorted bent 120 degrees geometry to one Ba(1) and one Se(1) atom. is represented by the CIF card [CIF]
