The material structure described by Li2Cr(CO3)3 crystallizes in the orthorhombic Ama2 space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. In the second Li site, Li(2) is bonded in a 3-coordinate geometry to one O(5), one O(6), and two equivalent O(1) atoms. Cr(1) is bonded in an octahedral geometry to one O(4), one O(6), two equivalent O(2), and two equivalent O(3) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. In the second C site, C(2) is bonded in a trigonal planar geometry to one O(4), one O(5), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Li(1), one Li(2), and one C(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Li(1), one Cr(1), and one C(1) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Cr(1) and one C(1) atom. In the fourth O site, O(4) is bonded in a distorted linear geometry to one Cr(1) and one C(2) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one Li(2) and one C(2) atom. In the sixth O site, O(6) is bonded in a 3-coordinate geometry to one Li(2), one Cr(1), and one C(2) atom. is represented by the CIF file [CIF]
