Li2C7H3O4CH crystallizes in the orthorhombic C222_1 space group. The structure consists of eight 02329_fluka molecules inside a Li2C7H3O4 framework. In the Li2C7H3O4 framework, there are three inequivalent Li sites. In the first Li site, Li(1) is bonded to one O(1), one O(2), and two equivalent O(4) atoms to form a mixture of distorted edge and corner-sharing LiO4 tetrahedra.

In the second Li site, Li(2) is bonded to two equivalent O(2) and two equivalent O(3) atoms to form distorted corner-sharing LiO4 tetrahedra. Both Li(2)-O(2) bond lengths are 1.97 Å. Both Li(2)-O(3) bond lengths are 1.95 Å. In the third Li site, Li(3) is bonded in an L-shaped geometry to two equivalent O(3) atoms. Both Li(3)-O(3) bond lengths are 1.96 Å. There are seven inequivalent C sites. In the first C site, C(2) is bonded in a single-bond geometry to one C(3) and one H(2) atom. The C(2)-C(3) bond length is 1.40 Å. The C(2)-H(2) bond length is 0.93 Å. In the second C site, C(3) is bonded in a trigonal planar geometry to one C(2), one C(4), and one C(7) atom. The C(3)-C(4) bond length is 1.38 Å. The C(3)-C(7) bond length is 1.51 Å. In the third C site, C(4) is bonded in a distorted single-bond geometry to one C(3), one C(5), and one H(3) atom. The C(4)-C(5) bond length is 1.39 Å. The C(4)-H(3) bond length is 0.93 Å. In the fourth 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 1.39 Å. The C(5)-C(8) bond length is 1.50 Å. In the fifth C site, C(6) is bonded in a distorted single-bond geometry to one C(5) and one H(4) atom. The C(6)-H(4) bond length is 0.93 Å. In the sixth C site, C(7) is bonded in a distorted bent 120 degrees geometry to one C(3), one O(1), and one O(2) atom. The C(7)-O(1) bond length is 1.25 Å. The C(7)-O(2) bond length is 1.25 Å. In the seventh C site, C(8) is bonded in a bent 120 degrees geometry to one C(5), one O(3), and one O(4) atom. The C(8)-O(3) bond length is 1.26 Å. The C(8)-O(4) bond length is 1.26 Å. There are three inequivalent H sites. In the first H site, H(2) is bonded in a single-bond geometry to one C(2) atom. In the second H site, H(3) 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. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Li(1) and one C(7) atom. In the second O site, O(3) is bonded in a distorted trigonal planar geometry to one Li(2), one Li(3), and one C(8) atom. In the third O site, O(4) is bonded in a distorted trigonal planar geometry to two equivalent Li(1) and one C(8) atom. In the fourth O site, O(2) is bonded in a distorted T-shaped geometry to one Li(1), one Li(2), and one C(7) atom. Linkers: 4 [O]C(=O)c1cccc(C([O])=O)c1. Metal clusters: 8 [Li].
