The compound described by MnCu2SbO4 crystallizes in the trigonal P-3m1 space group. Mn(1) is bonded to six equivalent O(1) atoms to form distorted edge-sharing MnO6 octahedra. Cu(1) is bonded in a linear geometry to one O(1) and one O(2) atom. Sb(1) is bonded to six equivalent O(2) atoms to form edge-sharing SbO6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Mn(1) and one Cu(1) atom to form OMn3Cu tetrahedra that share corners with nine equivalent O(1)Mn3Cu tetrahedra,  a cornercorner with one O(2)CuSb3 trigonal pyramid, and edges with three equivalent O(1)Mn3Cu tetrahedra. In the second O site, O(2) is bonded to one Cu(1) and three equivalent Sb(1) atoms to form distorted OCuSb3 trigonal pyramids that share  a cornercorner with one O(1)Mn3Cu tetrahedra, corners with nine equivalent O(2)CuSb3 trigonal pyramids, and edges with three equivalent O(2)CuSb3 trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
