The structure described by K2CoH2(SeO5)2 crystallizes in the triclinic P-1 space group. K(1) is bonded in a 8-coordinate geometry to one O(3), one O(5), two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms. Co(1) is bonded to two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms to form CoO6 octahedra that share corners with four equivalent Se(1)O4 tetrahedra. H(1) is bonded in a single-bond geometry to one O(1) and one O(5) atom. Se(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form SeO4 tetrahedra that share corners with two equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 47-54°. There are five inequivalent O sites. In the first O site, O(1) is bonded to two equivalent K(1), one H(1), and one Se(1) atom to form distorted edge-sharing OK2HSe tetrahedra. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent K(1) and one Se(1) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to one K(1), one Co(1), and one Se(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to two equivalent K(1), one Co(1), and one Se(1) atom. In the fifth O site, O(5) is bonded in a 2-coordinate geometry to one K(1), one Co(1), and one H(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
