The structure described by LiCH2O3 crystallizes in the orthorhombic Pna2_1 space group. Li(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form corner-sharing LiO4 tetrahedra. C(1) is bonded in a trigonal planar geometry to one H(1), one O(2), and one O(3) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(1) and one O(2) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Li(1) and one H(2) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Li(1), one C(1), and one H(2) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to two equivalent Li(1) and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
