The material described by Zn(CuO2)2 crystallizes in the tetragonal I4_1/a space group. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. Zn(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. O(1) is bonded to two equivalent Cu(1) and two equivalent Zn(1) atoms to form a mixture of distorted edge and corner-sharing OZn2Cu2 tetrahedra. is represented by the CIF file [CIF]
