Nd(CuO2)2 crystallizes in the monoclinic C2/c space group. Nd(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 Nd(1), one Cu(1), and one Cu(2) atom to form a mixture of corner and edge-sharing ONd2Cu2 tetrahedra. In the second O site, O(2) is bonded to two equivalent Nd(1), one Cu(1), and one Cu(2) atom to form a mixture of distorted corner and edge-sharing ONd2Cu2 tetrahedra.
Nd(CuO2)2 crystallizes in the monoclinic C2/c space group. Nd(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. There are two shorter (2.45 Å) and two longer (2.48 Å) Nd(1)-O(1) bond lengths. There are two shorter (2.46 Å) and two longer (2.47 Å) Nd(1)-O(2) bond lengths. 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. Both Cu(1)-O(1) bond lengths are 1.85 Å. Both Cu(1)-O(2) bond lengths are 1.86 Å. 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. Both Cu(2)-O(1) bond lengths are 1.93 Å. Both Cu(2)-O(2) bond lengths are 1.92 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Nd(1), one Cu(1), and one Cu(2) atom to form a mixture of corner and edge-sharing ONd2Cu2 tetrahedra. In the second O site, O(2) is bonded to two equivalent Nd(1), one Cu(1), and one Cu(2) atom to form a mixture of distorted corner and edge-sharing ONd2Cu2 tetrahedra.
