Cu(OOCC6H4COO)(C4H4O)2 is Indium-derived structured and crystallizes in the tetragonal P4/nbm space group. The structure is zero-dimensional and consists of eight (1e,3e)-1,4-dimethoxy-2,3-dimethylbuta-1,3-diene molecules and four Cu(OOCC6H4COO) clusters. In each Cu(OOCC6H4COO) cluster, 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 1.96 Å. Both Cu(1)-O(2) bond lengths are 1.97 Å. There are four inequivalent C sites. In the first C site, C(1) is bonded in a bent 120 degrees geometry to one C(2), one O(1), and one O(2) atom. The C(1)-C(2) bond length is 1.50 Å. The C(1)-O(1) bond length is 1.25 Å. The C(1)-O(2) bond length is 1.25 Å. In the second C site, C(2) is bonded in a trigonal planar geometry to one C(1), one C(3), and one C(7) atom. The C(2)-C(3) bond length is 1.38 Å. The C(2)-C(7) bond length is 1.38 Å. In the third C site, C(3) is bonded in a single-bond geometry to one C(2) and one H(1) atom. The C(3)-H(1) bond length is 0.93 Å. In the fourth C site, C(7) is bonded in a distorted single-bond geometry to one C(2) and one H(3) atom. The C(7)-H(3) bond length is 0.93 Å. There are two inequivalent H sites. In the first H site, H(3) is bonded in a single-bond geometry to one C(7) atom. In the second H site, H(1) is bonded in a single-bond geometry to one C(3) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Cu(1) and one C(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Cu(1) and one C(1) atom.
