The crystal structure described by Li2CO3 is Clathrate-derived structured and crystallizes in the monoclinic C2/c space group. Li(1) is bonded to one O(1) and three equivalent O(2) atoms to form a mixture of edge and corner-sharing LiO4 tetrahedra. C(1) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent Li(1) and one C(1) atom. In the second O site, O(2) is bonded to three equivalent Li(1) and one C(1) atom to form a mixture of distorted edge and corner-sharing OLi3C tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
