The compound described by CoH4SeO5 crystallizes in the monoclinic P2_1/c space group. Co(1) is bonded to one O(3), one O(4), one O(5), and two equivalent O(2) atoms to form edge-sharing CoO5 trigonal bipyramids. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) atom. In the second H site, H(2) is bonded in a distorted linear geometry to one O(3) and one O(4) atom. In the third H site, H(3) is bonded in a distorted single-bond geometry to one O(1) and one O(4) atom. In the fourth H site, H(4) is bonded in a distorted single-bond geometry to one O(1) and one O(5) atom. Se(1) is bonded in a trigonal non-coplanar geometry to one O(2), one O(3), and one O(5) atom. There are five inequivalent O sites. In the first O site, O(3) is bonded in a trigonal planar geometry to one Co(1), one H(2), and one Se(1) atom. In the second O site, O(4) is bonded in a distorted water-like geometry to one Co(1), one H(2), and one H(3) atom. In the third O site, O(5) is bonded in a 3-coordinate geometry to one Co(1), one H(4), and one Se(1) atom. In the fourth O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to one H(1), one H(3), and one H(4) atom. In the fifth O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Co(1) and one Se(1) atom. is represented by the CIF card [CIF]
