The compound described by K2CoH2(SO4)2 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. Co(1) is bonded to two equivalent H(1), two equivalent O(2), and two equivalent O(3) atoms to form CoH2O4 octahedra that share corners with four equivalent S(1)O4 tetrahedra. H(1) is bonded in a single-bond geometry to one Co(1) atom. S(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form SO4 tetrahedra that share corners with two equivalent Co(1)H2O4 octahedra. The corner-sharing octahedral tilt angles range from 39-59°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent K(1) and one S(1) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to two equivalent K(1), one Co(1), and one S(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to two equivalent K(1), one Co(1), and one S(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent K(1) and one S(1) atom. is represented by the CIF card [CIF]
