The material described by K2LiH2(SeO3)2 crystallizes in the triclinic P-1 space group. K(1) is bonded in a 8-coordinate geometry to one H(1), two equivalent O(1), two equivalent O(2), and three equivalent O(3) atoms. Li(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. H(1) is bonded in a single-bond geometry to one K(1) and one O(1) atom. Se(1) is bonded in a 3-coordinate geometry to one O(1), one O(2), and one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 1-coordinate geometry to two equivalent K(1), one Li(1), one H(1), and one Se(1) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to two equivalent K(1), one Li(1), and one Se(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to three equivalent K(1) and one Se(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
