MnCoO4 is Hydrophilite-derived structured and crystallizes in the orthorhombic Cmmm space group. Mn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form MnO6 octahedra that share corners with eight equivalent Co(1)O6 octahedra and edges with two equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 50-51°. Co(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CoO6 octahedra that share corners with eight equivalent Mn(1)O6 octahedra and edges with two equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 50-51°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Mn(1) and two equivalent Co(1) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to two equivalent Mn(1) and one Co(1) atom.
