The compound described by CoH6(SeO4)2 crystallizes in the monoclinic P2_1/c space group. Co(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms. There are three inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(2) and one O(3) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(1) and one O(4) atom. In the third H site, H(3) is bonded in a single-bond geometry to one O(4) atom. Se(1) is bonded in a trigonal non-coplanar geometry to one O(1), one O(2), and one O(3) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Co(1), one H(2), and one Se(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Co(1), one H(1), and one Se(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one H(1) and one Se(1) atom. In the fourth O site, O(4) is bonded in a distorted water-like geometry to one Co(1), one H(2), and one H(3) atom. is represented by the CIF file [CIF]
