CuMn2O4 is Spinel structured and crystallizes in the tetragonal I4_1/amd space group. Mn(1) is bonded to six equivalent O(1) atoms to form MnO6 octahedra that share corners with six equivalent Cu(1)O4 tetrahedra and edges with six equivalent Mn(1)O6 octahedra. Cu(1) is bonded to four equivalent O(1) atoms to form CuO4 tetrahedra that share corners with twelve equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 58-59°. O(1) is bonded to three equivalent Mn(1) and one Cu(1) atom to form a mixture of distorted edge and corner-sharing OMn3Cu trigonal pyramids.
CuMn2O4 is Spinel structured and crystallizes in the tetragonal I4_1/amd space group. Mn(1) is bonded to six equivalent O(1) atoms to form MnO6 octahedra that share corners with six equivalent Cu(1)O4 tetrahedra and edges with six equivalent Mn(1)O6 octahedra. There are two shorter (1.96 Å) and four longer (2.07 Å) Mn(1)-O(1) bond lengths. Cu(1) is bonded to four equivalent O(1) atoms to form CuO4 tetrahedra that share corners with twelve equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 58-59°. All Cu(1)-O(1) bond lengths are 2.00 Å. O(1) is bonded to three equivalent Mn(1) and one Cu(1) atom to form a mixture of distorted edge and corner-sharing OMn3Cu trigonal pyramids.
