The C(2)-C(3) bond length is 1.41 Å. The C(2)-C(7) bond length is 1.31 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 0.93 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 0.93 Å. In the fifth C site, C(10) is bonded in a distorted single-bond geometry to one C(11) and one H(6) atom. The C(10)-C(11) bond length is 1.37 Å. The C(10)-H(6) bond length is 0.93 Å. In the sixth C site, C(11) is bonded in a trigonal planar geometry to one C(10), one C(12), and one C(14) atom. The C(11)-C(12) bond length is 1.37 Å. The C(11)-C(14) bond length is 1.50 Å. In the seventh C site, C(12) is bonded in a distorted single-bond geometry to one C(11) and one H(7) atom. The C(12)-H(7) bond length is 0.93 Å. In the eighth C site, C(14) is bonded in a bent 120 degrees geometry to one C(11), one O(3), and one O(4) atom. The C(14)-O(3) bond length is 1.24 Å. The C(14)-O(4) bond length is 1.25 Å. There are four 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. In the third H site, H(6) is bonded in a single-bond geometry to one C(10) atom. In the fourth H site, H(7) is bonded in a single-bond geometry to one C(12) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in an L-shaped geometry to one In(1) and one C(1) atom. In the second O site, O(2) is bonded in an L-shaped geometry to one In(1) and one C(1) atom. In the third O site, O(3) is bonded in a distorted L-shaped geometry to one In(1) and one C(14) atom. In the fourth O site, O(4) is bonded in a distorted L-shaped geometry to one In(1) and one C(14) atom. Linkers: 8 [O]C(=O)c1ccc(-c2ccc(C([O])=O)cc2)cc1.
