The material structure described by Gd(CuO2)2 crystallizes in the monoclinic C2/c space group. Gd(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. In the second Cu site, Cu(2) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Gd(1), one Cu(1), and one Cu(2) atom to form a mixture of edge and corner-sharing OGd2Cu2 tetrahedra. In the second O site, O(2) is bonded to two equivalent Gd(1), one Cu(1), and one Cu(2) atom to form a mixture of distorted edge and corner-sharing OGd2Cu2 tetrahedra. is represented by the CIF file [CIF]
