The crystal structure described by K2Mn(SO6)2 crystallizes in the monoclinic C2/m space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a distorted hexagonal planar geometry to two equivalent O(1), two equivalent O(4), and two equivalent O(5) atoms. In the second K site, K(2) is bonded in a 6-coordinate geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(6) atoms. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a square co-planar geometry to four equivalent O(5) atoms. In the second Mn site, Mn(2) is bonded in a square co-planar geometry to four equivalent O(6) atoms. S(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are six inequivalent O sites. In the first O site, O(4) is bonded in a distorted single-bond geometry to one K(1) and one S(1) atom. In the second O site, O(5) is bonded in a distorted single-bond geometry to one K(1) and one Mn(1) atom. In the third O site, O(6) is bonded in a 3-coordinate geometry to one K(2), one Mn(2), and one O(6) atom. In the fourth O site, O(1) is bonded in a distorted single-bond geometry to one K(1) and one S(1) atom. In the fifth O site, O(2) is bonded in a distorted single-bond geometry to one K(2) and one S(1) atom. In the sixth O site, O(3) is bonded in a distorted linear geometry to one K(2) and one S(1) atom. is represented by the CIF file [CIF]
