LuCu(MoO4)2 crystallizes in the monoclinic C2/c space group. Lu(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted LuO6 octahedra that share corners with eight equivalent Mo(1)O6 octahedra and edges with two equivalent Cu(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 46-57°. Mo(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form distorted MoO6 octahedra that share corners with four equivalent Lu(1)O6 octahedra, corners with four equivalent Cu(1)O6 octahedra, and edges with two equivalent Mo(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-57°. Cu(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form distorted CuO6 octahedra that share corners with eight equivalent Mo(1)O6 octahedra and edges with two equivalent Lu(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-55°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Lu(1), one Mo(1), and one Cu(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Lu(1) and two equivalent Mo(1) atoms. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Lu(1), one Mo(1), and one Cu(1) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to two equivalent Mo(1) and one Cu(1) atom.
