K2V2Mn3CO11 crystallizes in the hexagonal P6_3/m space group. K(1) is bonded in a 9-coordinate geometry to three equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. V(1) is bonded to one O(1) and three equivalent O(3) atoms to form VO4 tetrahedra that share corners with six equivalent Mn(1)O6 octahedra and  a cornercorner with one Mn(2)O5 trigonal bipyramid. The corner-sharing octahedral tilt angles range from 51-55°. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to six equivalent O(3) atoms to form MnO6 octahedra that share corners with six equivalent V(1)O4 tetrahedra and edges with three equivalent Mn(1)O6 octahedra. In the second Mn site, Mn(2) is bonded to two equivalent O(1) and three equivalent O(2) atoms to form MnO5 trigonal bipyramids that share corners with two equivalent V(1)O4 tetrahedra. C(1) is bonded in a trigonal planar geometry to three equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to three equivalent K(1), one V(1), and one Mn(2) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent K(1), one Mn(2), and one C(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one K(1), one V(1), and two equivalent Mn(1) atoms.
