LaCrMnO6 crystallizes in the triclinic P1 space group. La(1) is bonded in a 12-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), two equivalent O(4), two equivalent O(5), and two equivalent O(6) atoms. Cr(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form distorted CrO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra.
