The structure described by MnMoO4 is Hydrophilite-derived structured and crystallizes in the triclinic P1 space group. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(7), and one O(8) atom to form distorted MoO6 octahedra that share corners with four equivalent Mn(1)O6 octahedra, corners with four equivalent Mn(2)O6 octahedra, and edges with two equivalent Mo(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 44-54°. In the second Mo site, Mo(2) 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 MoO6 octahedra that share corners with four equivalent Mn(1)O6 octahedra, corners with four equivalent Mn(2)O6 octahedra, and edges with two equivalent Mo(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 47-55°. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one O(1), one O(2), one O(5), one O(6), one O(7), and one O(8) atom to form distorted MnO6 octahedra that share corners with four equivalent Mo(1)O6 octahedra, corners with four equivalent Mo(2)O6 octahedra, and edges with two equivalent Mn(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 47-55°. In the second Mn site, Mn(2) is bonded to one O(3), one O(4), one O(5), one O(6), one O(7), and one O(8) atom to form MnO6 octahedra that share corners with four equivalent Mo(1)O6 octahedra, corners with four equivalent Mo(2)O6 octahedra, and edges with two equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 44-55°. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Mo(1), one Mo(2), and one Mn(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one Mo(1), one Mo(2), and one Mn(1) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to one Mo(1), one Mo(2), and one Mn(2) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to one Mo(1), one Mo(2), and one Mn(2) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one Mo(2), one Mn(1), and one Mn(2) atom. In the sixth O site, O(6) is bonded in a 3-coordinate geometry to one Mo(2), one Mn(1), and one Mn(2) atom. In the seventh O site, O(7) is bonded in a distorted trigonal planar geometry to one Mo(1), one Mn(1), and one Mn(2) atom. In the eighth O site, O(8) is bonded in a distorted trigonal planar geometry to one Mo(1), one Mn(1), and one Mn(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
