MnMoO4 crystallizes in the monoclinic P2/c space group. Mo(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted MoO6 octahedra that share corners with eight equivalent Mn(1)O6 octahedra and edges with two equivalent Mo(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 46-56°. Mn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form distorted MnO6 octahedra that share corners with eight equivalent Mo(1)O6 octahedra and edges with two equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 46-56°. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted trigonal planar geometry to one Mo(1) and two equivalent Mn(1) atoms. In the second O site, O(1) is bonded in a trigonal planar geometry to two equivalent Mo(1) and one Mn(1) atom.
