TiV4MnO12 crystallizes in the monoclinic C2 space group. Ti(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(6) atoms to form TiO6 octahedra that share corners with two equivalent V(1)O4 tetrahedra, corners with four equivalent V(2)O4 tetrahedra, and edges with two equivalent Mn(1)O6 octahedra. 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 Ti(1)O6 octahedra, corners with two equivalent Mn(1)O6 octahedra, and corners with two equivalent V(2)O4 tetrahedra.
