The material structure described by K2Mn(SO6)2 crystallizes in the monoclinic C2/m space group. K(1) is bonded in a 9-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), one O(6), one O(7), one O(8), and one O(9) atom. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to two equivalent O(3), two equivalent O(8), and two equivalent O(9) atoms to form MnO6 octahedra that share corners with two equivalent S(1)O4 tetrahedra.

There are two inequivalent S sites. In the first S site, S(1) is bonded to one O(3), one O(4), and two equivalent O(1) atoms to form SO4 tetrahedra that share  a cornercorner with one Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles are 22°. In the second S site, S(2) is bonded to one O(5), one O(6), and two equivalent O(2) atoms to form SO4 tetrahedra that share  a cornercorner with one Mn(2)O6 octahedra. The corner-sharing octahedral tilt angles are 45°. There are nine inequivalent O sites. In the first O site, O(5) is bonded in a 2-coordinate geometry to two equivalent K(1), one Mn(2), and one S(2) atom. In the second O site, O(6) is bonded in a distorted single-bond geometry to two equivalent K(1) and one S(2) atom.

In the sixth O site, O(1) is bonded in a distorted single-bond geometry to one K(1) and one S(1) atom. In the seventh O site, O(2) is bonded in a distorted single-bond geometry to one K(1) and one S(2) atom. In the eighth O site, O(3) is bonded in a bent 150 degrees geometry to two equivalent K(1), one Mn(1), and one S(1) atom.
