Cu2ZnO3 crystallizes in the orthorhombic Pmmn space group. Cu(1) is bonded in a square co-planar geometry to one O(1) and three equivalent O(2) atoms. Zn(1) is bonded in a 4-coordinate 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 Cu(1) and two equivalent Zn(1) atoms to form corner-sharing OZn2Cu2 tetrahedra. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to three equivalent Cu(1) and one Zn(1) atom.
Cu2ZnO3 crystallizes in the orthorhombic Pmmn space group. Cu(1) is bonded in a square co-planar geometry to one O(1) and three equivalent O(2) atoms. The Cu(1)-O(1) bond length is 1.93 Å. There is one shorter (1.95 Å) and two longer (1.98 Å) Cu(1)-O(2) bond lengths. Zn(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. Both Zn(1)-O(1) bond lengths are 2.07 Å. Both Zn(1)-O(2) bond lengths are 2.10 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Cu(1) and two equivalent Zn(1) atoms to form corner-sharing OZn2Cu2 tetrahedra. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to three equivalent Cu(1) and one Zn(1) atom.
