The material structure described by K2V4MnO12 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 9-coordinate geometry to one O(3), one O(4), one O(6), two equivalent O(1), two equivalent O(2), and two equivalent O(5) atoms. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(1), one O(2), one O(5), and one O(6) atom to form VO4 tetrahedra that share  a cornercorner with one Mn(1)O6 octahedra and corners with two equivalent V(2)O4 tetrahedra. The corner-sharing octahedral tilt angles are 22°. In the second V site, V(2) is bonded to one O(3), one O(4), one O(5), and one O(6) atom to form VO4 tetrahedra that share corners with two equivalent Mn(1)O6 octahedra and corners with two equivalent V(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 20-29°. Mn(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form MnO6 octahedra that share corners with two equivalent V(1)O4 tetrahedra and corners with four equivalent V(2)O4 tetrahedra. There are six inequivalent O sites. In the first O site, O(6) is bonded in a 3-coordinate geometry to one K(1), one V(1), and one V(2) atom. In the second O site, O(1) is bonded in a distorted single-bond geometry to two equivalent K(1) and one V(1) atom. In the third O site, O(2) is bonded in a 2-coordinate geometry to two equivalent K(1), one V(1), and one Mn(1) atom. In the fourth O site, O(3) is bonded in a 3-coordinate geometry to one K(1), one V(2), and one Mn(1) atom. In the fifth O site, O(4) is bonded in a 3-coordinate geometry to one K(1), one V(2), and one Mn(1) atom. In the sixth O site, O(5) is bonded in a distorted bent 150 degrees geometry to two equivalent K(1), one V(1), and one V(2) atom. is represented by the CIF file [CIF]
