The structure described by K2CoH2(SO5)2 crystallizes in the triclinic P-1 space group. K(1) is bonded in a 7-coordinate geometry to two equivalent H(1), one O(1), one O(2), one O(4), and two equivalent O(3) atoms. Co(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form distorted CoO6 octahedra that share corners with four equivalent S(1)O4 tetrahedra. H(1) is bonded in a 3-coordinate geometry to two equivalent K(1) and one H(1) atom. S(1) is bonded to one O(2), one O(3), one O(4), and one O(5) atom to form SO4 tetrahedra that share corners with two equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 36-70°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one K(1), one Co(1), and one O(5) atom. In the second O site, O(2) is bonded in a 1-coordinate geometry to one K(1), one Co(1), and one S(1) atom. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to two equivalent K(1) and one S(1) atom. In the fourth O site, O(4) is bonded in a 1-coordinate geometry to one K(1), one Co(1), and one S(1) atom. In the fifth O site, O(5) is bonded in a distorted single-bond geometry to one S(1) and one O(1) atom. is represented by the CIF card [CIF]
