The material structure described by NiCu2O4 crystallizes in the tetragonal I4_1/a space group. Ni(1) is bonded in a distorted square co-planar geometry to four equivalent O(1) atoms. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded in a distorted trigonal non-coplanar geometry to one Ni(1) and two equivalent Cu(1) atoms. is represented by the CIF card [CIF]
