LiC7H4O4CH crystallizes in the monoclinic P2_1/c space group. The structure consists of four 02329_fluka molecules inside a LiC7H4O4 framework. In the LiC7H4O4 framework, Li(1) is bonded to one O(2), one O(4), and two equivalent O(1) atoms to form distorted edge-sharing LiO4 tetrahedra. The Li(1)-O(2) bond length is 2.04 Å. The Li(1)-O(4) bond length is 1.93 Å. There is one shorter (1.92 Å) and one longer (1.97 Å) Li(1)-O(1) bond length. There are seven inequivalent C sites. In the first C site, C(3) is bonded in a trigonal planar geometry to one C(2), one C(4), and one C(8) atom. The C(3)-C(2) bond length is 1.40 Å. The C(3)-C(4) bond length is 1.40 Å. The C(3)-C(8) bond length is 1.48 Å. In the second C site, C(4) is bonded in a distorted single-bond geometry to one C(3) and one H(2) atom. The C(4)-H(2) bond length is 1.09 Å. In the third C site, C(6) is bonded in a distorted single-bond geometry to one C(1) and one H(4) atom. The C(6)-C(1) bond length is 1.40 Å. The C(6)-H(4) bond length is 1.09 Å. In the fourth C site, C(7) is bonded in a distorted bent 120 degrees geometry to one C(1), one O(1), and one O(2) atom. The C(7)-C(1) bond length is 1.50 Å. The C(7)-O(1) bond length is 1.27 Å. The C(7)-O(2) bond length is 1.28 Å. In the fifth C site, C(8) is bonded in a distorted bent 120 degrees geometry to one C(3), one O(3), and one O(4) atom. The C(8)-O(3) bond length is 1.33 Å. The C(8)-O(4) bond length is 1.24 Å. In the sixth C site, C(1) is bonded in a trigonal planar geometry to one C(2), one C(6), and one C(7) atom. The C(1)-C(2) bond length is 1.40 Å. In the seventh C site, C(2) is bonded in a distorted single-bond geometry to one C(1), one C(3), and one H(1) atom. The C(2)-H(1) bond length is 1.09 Å. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(2) 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(4) is bonded in a single-bond geometry to one C(6) atom. In the fourth H site, H(5) is bonded in a distorted linear geometry to one O(2) and one O(3) atom. The H(5)-O(2) bond length is 1.55 Å. The H(5)-O(3) bond length is 1.03 Å. There are four inequivalent O sites. In the first O site, O(3) is bonded in a water-like geometry to one C(8) and one H(5) atom. In the second O site, O(4) is bonded in a bent 150 degrees geometry to one Li(1) and one C(8) atom. In the third O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Li(1), one C(7), and one H(5) atom. In the fourth O site, O(1) is bonded in a distorted T-shaped geometry to two equivalent Li(1) and one C(7) atom. Linkers: 4 [O]C(=O)c1cccc(C(=O)O)c1. Metal clusters: 4 [Li].
