Li2C3H6O7CH2 crystallizes in the monoclinic P2_1/c space group. The structure consists of four 02329_fluka molecules inside a Li2C3H6O7 framework. In the Li2C3H6O7 framework, there are two inequivalent Li sites. In the first Li site, Li(1) is bonded to one O(2), one O(6), one O(7), and two equivalent O(3) atoms to form LiO5 trigonal bipyramids that share  a cornercorner with one Li(2)O4 tetrahedra and  an edgeedge with one Li(1)O5 trigonal bipyramid. The Li(1)-O(2) bond length is 1.99 Å. The Li(1)-O(6) bond length is 1.92 Å. The Li(1)-O(7) bond length is 2.20 Å. There is one shorter (2.03 Å) and one longer (2.11 Å) Li(1)-O(3) bond length. In the second Li site, Li(2) is bonded to one O(1), one O(4), one O(5), and one O(7) atom to form corner-sharing LiO4 tetrahedra. The Li(2)-O(1) bond length is 1.94 Å. The Li(2)-O(4) bond length is 1.98 Å. The Li(2)-O(5) bond length is 1.93 Å. The Li(2)-O(7) bond length is 1.96 Å. There are three inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. The C(1)-O(1) bond length is 1.27 Å. The C(1)-O(2) bond length is 1.26 Å. In the second C site, C(2) is bonded in a distorted water-like geometry to one H(1) and one O(3) atom. The C(2)-H(1) bond length is 1.10 Å. The C(2)-O(3) bond length is 1.43 Å. In the third C site, C(4) is bonded in a distorted bent 120 degrees geometry to one O(4) and one O(5) atom. The C(4)-O(4) bond length is 1.28 Å. The C(4)-O(5) bond length is 1.27 Å. There are six inequivalent H sites. In the first H site, H(7) is bonded in a distorted single-bond geometry to one O(5) and one O(7) atom. The H(7)-O(5) bond length is 1.68 Å. The H(7)-O(7) bond length is 1.01 Å. In the second H site, H(8) is bonded in a single-bond geometry to one O(7) atom. The H(8)-O(7) bond length is 0.99 Å. In the third H site, H(1) is bonded in a single-bond geometry to one C(2) atom. In the fourth H site, H(2) is bonded in a distorted linear geometry to one O(1) and one O(3) atom. The H(2)-O(1) bond length is 1.61 Å. The H(2)-O(3) bond length is 1.01 Å. In the fifth H site, H(5) is bonded in a single-bond geometry to one O(2) and one O(6) atom. The H(5)-O(2) bond length is 1.71 Å. The H(5)-O(6) bond length is 1.00 Å. In the sixth H site, H(6) is bonded in a single-bond geometry to one O(6) atom. The H(6)-O(6) bond length is 0.98 Å. There are seven inequivalent O sites. In the first O site, O(3) is bonded to two equivalent Li(1), one C(2), and one H(2) atom to form distorted OLi2HC tetrahedra that share corners with two equivalent O(7)Li2H2 tetrahedra and  an edgeedge with one O(3)Li2HC tetrahedra. In the second O site, O(4) is bonded in a bent 120 degrees geometry to one Li(2) and one C(4) atom. In the third O site, O(5) is bonded in a distorted trigonal planar geometry to one Li(2), one C(4), and one H(7) atom. In the fourth O site, O(2) is bonded in a distorted trigonal planar geometry to one Li(1), one C(1), and one H(5) atom. In the fifth O site, O(6) is bonded in a distorted trigonal planar geometry to one Li(1), one H(5), and one H(6) atom. In the sixth O site, O(7) is bonded to one Li(1), one Li(2), one H(7), and one H(8) atom to form distorted corner-sharing OLi2H2 tetrahedra. In the seventh O site, O(1) is bonded in a distorted T-shaped geometry to one Li(2), one C(1), and one H(2) atom. Linkers: 2 [O]C(=O)C[C@H](O)C([O])=O ,2 [O]C(=O)C[C@@H](O)C([O])=O.
