The C(2)-O(3) bond length is 1.39 Å. In the second C site, C(3) is bonded in a trigonal planar geometry to one C(11), one C(2), and one C(8) atom. The C(3)-C(11) bond length is 1.37 Å. The C(3)-C(8) bond length is 1.47 Å. In the third C site, C(7) is bonded in a distorted single-bond geometry to one C(8) and one H(3) atom. The C(7)-C(8) bond length is 1.38 Å. The C(7)-H(3) bond length is 0.93 Å. In the fourth C site, C(8) is bonded in a trigonal planar geometry to one C(3), one C(7), and one C(9) atom. The C(8)-C(9) bond length is 1.40 Å. In the fifth C site, C(10) is bonded in a trigonal planar geometry to one C(10) and two equivalent C(2) atoms. The C(10)-C(10) bond length is 1.51 Å. In the sixth C site, C(11) is bonded in a single-bond geometry to two equivalent C(3) and one H(5) atom. The C(11)-H(5) bond length is 0.93 Å. In the seventh C site, C(9) is bonded in a distorted single-bond geometry to one C(8) and one H(4) atom. The C(9)-H(4) bond length is 0.93 Å. There are three inequivalent H sites.
