The crystal structure described by Li2Cr(CO3)2 crystallizes in the orthorhombic Fdd2 space group. Li(1) is bonded in a 4-coordinate geometry to one O(2), two equivalent O(1), and two equivalent O(3) atoms. Cr(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. C(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Li(1), one Cr(1), and one C(1) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Li(1), one Cr(1), and one C(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to two equivalent Li(1), one Cr(1), and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
