In each CuC4H4O5 cluster, Cu(1) is bonded in a distorted square pyramidal geometry to one O(1), one O(2), one O(3), one O(4), and one O(5) atom. The Cu(1)-O(1) bond length is 1.99 Å. The Cu(1)-O(2) bond length is 1.99 Å. The Cu(1)-O(3) bond length is 2.00 Å. The Cu(1)-O(4) bond length is 1.99 Å. The Cu(1)-O(5) bond length is 2.29 Å. There are four inequivalent C sites. In the first C site, C(4) is bonded in a distorted bent 120 degrees geometry to one O(3) and one O(4) atom. The C(4)-O(3) bond length is 1.27 Å. The C(4)-O(4) bond length is 1.28 Å. In the second C site, C(7) is bonded in a distorted trigonal non-coplanar geometry to one H(11), one H(12), and one O(5) atom. The C(7)-H(11) bond length is 1.10 Å. The C(7)-H(12) bond length is 1.10 Å. The C(7)-O(5) bond length is 1.44 Å. In the third C site, C(8) is bonded in a distorted trigonal non-coplanar geometry to one H(13), one H(14), and one O(5) atom. The C(8)-H(13) bond length is 1.10 Å. The C(8)-H(14) bond length is 1.10 Å. The C(8)-O(5) bond length is 1.44 Å. In the fourth C site, C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. The C(1)-O(1) bond length is 1.28 Å. The C(1)-O(2) bond length is 1.28 Å. There are four inequivalent H sites. In the first H site, H(11) is bonded in a single-bond geometry to one C(7) atom. In the second H site, H(12) is bonded in a single-bond geometry to one C(7) atom. In the third H site, H(13) is bonded in a single-bond geometry to one C(8) atom. In the fourth H site, H(14) is bonded in a single-bond geometry to one C(8) atom. There are five inequivalent O sites. In the first O site, O(2) is bonded in a bent 120 degrees geometry to one Cu(1) and one C(1) atom. In the second O site, O(3) is bonded in a bent 120 degrees geometry to one Cu(1) and one C(4) atom.
