In the sixth C site, C(7) is bonded in a distorted single-bond geometry to one C(2), one C(6), and one H(3) atom. The C(7)-H(3) bond length is 0.93 Å. In the seventh C site, C(8) is bonded in a bent 120 degrees geometry to one C(6), one O(3), and one O(4) atom. The C(8)-O(3) bond length is 1.27 Å. The C(8)-O(4) bond length is 1.27 Å. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(3) atom. In the second H site, H(3) is bonded in a single-bond geometry to one C(7) atom. There are six inequivalent O sites. In the first O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to one Cu(2) and two equivalent Cu(1) atoms. In the second O site, O(1) is bonded in a bent 120 degrees geometry to one Cu(1) and one C(1) atom.
