LiMnCAsO7 crystallizes in the monoclinic P2_1 space group. Li(1) is bonded in a distorted pentagonal planar geometry to one O(1), one O(2), one O(3), one O(5), and one O(6) atom. Mn(1) is bonded to one O(2), one O(3), one O(4), one O(5), one O(6), and one O(7) atom to form MnO6 octahedra that share corners with four equivalent As(1)O4 tetrahedra. C(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. As(1) is bonded to one O(4), one O(5), one O(6), and one O(7) atom to form AsO4 tetrahedra that share corners with four equivalent Mn(1)O6 octahedra.
