Nb(Cu3O4)2 crystallizes in the cubic Fm-3m space group. Nb(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to one Nb(1) and three equivalent Cu(1) atoms to form a mixture of corner and edge-sharing ONbCu3 tetrahedra.
