Cu2Zn2O5 is Aluminum carbonitride-like structured and crystallizes in the orthorhombic Pbam space group. Cu(1) is bonded to one O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted corner-sharing CuO5 trigonal bipyramids. Zn(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Cu(1) and four equivalent Zn(1) atoms to form OZn4Cu2 octahedra that share corners with eight equivalent O(2)Zn2Cu2 tetrahedra, corners with four equivalent O(3)Zn2Cu2 trigonal pyramids, edges with two equivalent O(1)Zn4Cu2 octahedra, edges with two equivalent O(2)Zn2Cu2 tetrahedra, and edges with four equivalent O(3)Zn2Cu2 trigonal pyramids. In the second O site, O(2) is bonded to two equivalent Cu(1) and two equivalent Zn(1) atoms to form OZn2Cu2 tetrahedra that share corners with four equivalent O(1)Zn4Cu2 octahedra, corners with four equivalent O(2)Zn2Cu2 tetrahedra, corners with four equivalent O(3)Zn2Cu2 trigonal pyramids,  an edgeedge with one O(1)Zn4Cu2 octahedra, and edges with two equivalent O(3)Zn2Cu2 trigonal pyramids. The corner-sharing octahedral tilt angles range from 18-61°. In the third O site, O(3) is bonded to two equivalent Cu(1) and two equivalent Zn(1) atoms to form distorted OZn2Cu2 trigonal pyramids that share corners with two equivalent O(1)Zn4Cu2 octahedra, corners with four equivalent O(2)Zn2Cu2 tetrahedra, corners with two equivalent O(3)Zn2Cu2 trigonal pyramids, edges with two equivalent O(1)Zn4Cu2 octahedra, edges with two equivalent O(2)Zn2Cu2 tetrahedra, and  an edgeedge with one O(3)Zn2Cu2 trigonal pyramid. The corner-sharing octahedral tilt angles are 58°.
Cu2Zn2O5 is Aluminum carbonitride-like structured and crystallizes in the orthorhombic Pbam space group. Cu(1) is bonded to one O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted corner-sharing CuO5 trigonal bipyramids. The Cu(1)-O(1) bond length is 2.03 Å. Both Cu(1)-O(2) bond lengths are 2.01 Å. Both Cu(1)-O(3) bond lengths are 1.85 Å. Zn(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Both Zn(1)-O(1) bond lengths are 2.41 Å. Both Zn(1)-O(2) bond lengths are 2.07 Å. There is one shorter (2.06 Å) and one longer (2.23 Å) Zn(1)-O(3) bond length. There are three inequivalent O sites.
