The C(4)-C(5) bond length is 1.42 Å. The C(4)-H(2) bond length is 0.95 Å. In the third C site, C(5) is bonded in a trigonal planar geometry to one C(4), one C(6), and one C(8) atom. The C(5)-C(6) bond length is 1.37 Å. The C(5)-C(8) bond length is 1.49 Å. In the fourth C site, C(6) is bonded in a distorted single-bond geometry to one C(5) and one H(3) atom. The C(6)-H(3) bond length is 0.95 Å. In the fifth C site, C(8) is bonded in a trigonal planar geometry to one C(5), one C(8), and one C(9) atom. The C(8)-C(8) bond length is 1.44 Å. There are three inequivalent H sites. In the first H site, H(5) is bonded in a single-bond geometry to one C(9) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(4) atom. In the third H site, H(3) is bonded in a single-bond geometry to one C(6) atom. In each ZnC8H4O4 cluster, Zn(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. Both Zn(1)-O(1) bond lengths are 2.04 Å. Both Zn(1)-O(2) bond lengths are 2.04 Å. There are four inequivalent C sites. In the first C site, C(1) is bonded in a distorted 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 1.24 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 1.39 Å. The C(2)-C(7) bond length is 1.38 Å. In the third C site, C(3) is bonded in a distorted single-bond geometry to one C(2) and one H(1) atom. The C(3)-H(1) bond length is 0.95 Å. In the fourth C site, C(7) is bonded in a distorted single-bond geometry to one C(2) and one H(4) atom. The C(7)-H(4) bond length is 0.95 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(4) is bonded in a single-bond geometry to one C(7) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Zn(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Zn(1) and one C(1) atom.
