Zn(CuO2)2 is Spinel-like structured and crystallizes in the orthorhombic Imma space group. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form CuO4 tetrahedra that share corners with six equivalent Cu(2)O6 octahedra and corners with six equivalent Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 55-60°. In the second Cu site, Cu(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CuO6 octahedra that share corners with six equivalent Cu(1)O4 tetrahedra, edges with two equivalent Cu(2)O6 octahedra, and edges with four equivalent Zn(1)O6 octahedra. Zn(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form ZnO6 octahedra that share corners with six equivalent Cu(1)O4 tetrahedra, edges with two equivalent Zn(1)O6 octahedra, and edges with four equivalent Cu(2)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Cu(1), one Cu(2), and two equivalent Zn(1) atoms to form a mixture of distorted edge and corner-sharing OZn2Cu2 trigonal pyramids. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Cu(1), two equivalent Cu(2), and one Zn(1) atom.
