NiCuO2 crystallizes in the monoclinic C2/m space group. Ni(1) is bonded to six equivalent O(1) atoms to form edge-sharing NiO6 octahedra. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to three equivalent Ni(1) and two equivalent Cu(1) atoms to form a mixture of distorted corner and edge-sharing OCu2Ni3 square pyramids.
NiCuO2 crystallizes in the monoclinic C2/m space group. Ni(1) is bonded to six equivalent O(1) atoms to form edge-sharing NiO6 octahedra. There are two shorter (2.08 Å) and four longer (2.10 Å) Ni(1)-O(1) bond lengths. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. All Cu(1)-O(1) bond lengths are 1.99 Å. O(1) is bonded to three equivalent Ni(1) and two equivalent Cu(1) atoms to form a mixture of distorted corner and edge-sharing OCu2Ni3 square pyramids.
