The compound described by Li2V4MnCuO12 crystallizes in the monoclinic C2 space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent O(2) and two equivalent O(3) atoms. In the second Li site, Li(2) is bonded in a see-saw-like geometry to two equivalent O(1) and two equivalent O(6) 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(4), and one O(5) atom to form VO4 tetrahedra that share  a cornercorner with one Mn(1)O6 octahedra, corners with two equivalent Cu(1)O6 octahedra, and corners with two equivalent V(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 38-63°. 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  a cornercorner with one Cu(1)O6 octahedra, 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 37-61°. Mn(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(6) atoms to form MnO6 octahedra that share corners with two equivalent V(1)O4 tetrahedra, corners with four equivalent V(2)O4 tetrahedra, and edges with two equivalent Cu(1)O6 octahedra. Cu(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form CuO6 octahedra that share corners with two equivalent V(2)O4 tetrahedra, corners with four equivalent V(1)O4 tetrahedra, and edges with two equivalent Mn(1)O6 octahedra. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Li(2), one V(1), one Mn(1), and one Cu(1) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Li(1), one V(1), and one Cu(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Li(1), one V(2), one Mn(1), and one Cu(1) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one V(1) and one V(2) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one V(1) and one V(2) atom. In the sixth O site, O(6) is bonded in a distorted T-shaped geometry to one Li(2), one V(2), and one Mn(1) atom. is represented by the CIF file [CIF]
