There are seven inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one C(10), one C(4), and one C(9) atom. The C(1)-C(10) bond length is 1.51 Å. The C(1)-C(4) bond length is 1.37 Å. The C(1)-C(9) bond length is 1.42 Å. In the second C site, C(2) is bonded in a distorted single-bond geometry to one O(8) atom. The C(2)-O(8) bond length is 1.41 Å. In the third C site, C(4) is bonded in a distorted single-bond geometry to one C(1) and one H(3) atom. The C(4)-H(3) bond length is 0.93 Å. In the fourth C site, C(6) is bonded in a distorted trigonal non-coplanar geometry to one C(11); two equivalent H(4,5); and one O(8) atom. The C(6)-C(11) bond length is 1.50 Å. Both C(6)-H(4,5) bond lengths are 0.97 Å. The C(6)-O(8) bond length is 1.44 Å. In the fifth C site, C(9) is bonded in a distorted single-bond geometry to one C(1) and one H(7) atom. The C(9)-H(7) bond length is 0.93 Å. In the sixth C site, C(10) is bonded in a distorted bent 120 degrees geometry to one C(1), one O(2), and one O(4) atom. The C(10)-O(2) bond length is 1.23 Å. The C(10)-O(4) bond length is 1.26 Å. In the seventh C site, C(11) is bonded in a distorted trigonal planar geometry to one C(6), one O(3), and one O(5) atom. The C(11)-O(3) bond length is 1.25 Å. The C(11)-O(5) bond length is 1.26 Å. There are three inequivalent H sites. In the first H site, H(3) is bonded in a single-bond geometry to one C(4) atom. In the second H site, H(4,5) is bonded in a single-bond geometry to one C(6) atom. In the third H site, H(7) is bonded in a single-bond geometry to one C(9) atom. There are five inequivalent O sites. In the first O site, O(2) is bonded in a single-bond geometry to one C(10) atom. In the second O site, O(3) is bonded in a distorted water-like geometry to one Pb(1) and one C(11) atom. In the third O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Pb(1) and one C(10) atom. In the fourth O site, O(5) is bonded in a single-bond geometry to one C(11) atom. In the fifth O site, O(8) is bonded in a bent 120 degrees geometry to one C(2) and one C(6) atom. Linkers: 2 [O]C(=O)COc1cc(OCC([O])=O)cc(C([O])=O)c1. Metal clusters: 2 O=[C]O[Pb]O[C]=O.
