The compound described by K2Co(SO7)2 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 8-coordinate geometry to one O(2), one O(5), one O(6), one O(7), two equivalent O(1), and two equivalent O(4) atoms. Co(1) is bonded in an octahedral geometry to two equivalent O(3), two equivalent O(6), and two equivalent O(7) atoms. S(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(4), and one O(5) atom. There are seven inequivalent O sites. In the first O site, O(7) is bonded in a distorted single-bond geometry to one K(1) and one Co(1) atom. In the second O site, O(1) is bonded in a distorted single-bond geometry to two equivalent K(1) and one S(1) atom. In the third O site, O(2) is bonded in a distorted single-bond geometry to one K(1) and one S(1) atom. In the fourth O site, O(3) is bonded in a single-bond geometry to one Co(1) atom. In the fifth O site, O(4) is bonded in a single-bond geometry to two equivalent K(1) and one S(1) atom. In the sixth O site, O(5) is bonded in a distorted bent 120 degrees geometry to one K(1) and one S(1) atom. In the seventh O site, O(6) is bonded in a distorted single-bond geometry to one K(1) and one Co(1) atom. is represented by the CIF file [CIF]
