The compound described by Zn(CuO2)2 crystallizes in the orthorhombic Pbcm space group. Cu(1) is bonded in a distorted rectangular see-saw-like geometry to one O(2), one O(3), and two equivalent O(1) atoms. Zn(1) is bonded in a 8-coordinate geometry to two equivalent O(2), two equivalent O(3), and four equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Cu(1) and two equivalent Zn(1) atoms. In the second O site, O(2) is bonded in a distorted water-like geometry to two equivalent Cu(1) and two equivalent Zn(1) atoms. In the third O site, O(3) is bonded to two equivalent Cu(1) and two equivalent Zn(1) atoms to form corner-sharing OZn2Cu2 tetrahedra. is represented by the CIF file [CIF]
