The material structure described by Li2V(CO3)2 crystallizes in the orthorhombic Fdd2 space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to one O(1), one O(2), one O(4), and one O(6) atom to form distorted LiO4 trigonal pyramids that share corners with two equivalent V(1)O6 octahedra and  an edgeedge with one V(1)O6 octahedra. The corner-sharing octahedral tilt angles are 85°. In the second Li site, Li(2) is bonded in a distorted rectangular see-saw-like geometry to one O(2), one O(3), one O(5), and one O(6) atom. V(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form VO6 octahedra that share corners with two equivalent Li(1)O4 trigonal pyramids and  an edgeedge with one Li(1)O4 trigonal pyramid. There are two inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one O(2), one O(3), and one O(4) atom. In the second C site, C(2) is bonded in a trigonal planar geometry to one O(1), 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 trigonal planar geometry to one Li(1), one V(1), and one C(2) atom. In the second O site, O(2) is bonded in a distorted square co-planar geometry to one Li(1), one Li(2), one V(1), and one C(1) atom. In the third O site, O(3) is bonded in a distorted T-shaped geometry to one Li(2), one V(1), and one C(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Li(1), one V(1), and one C(1) atom. In the fifth O site, O(5) is bonded in a distorted T-shaped geometry to one Li(2), one V(1), and one C(2) atom. In the sixth O site, O(6) is bonded in a 4-coordinate geometry to one Li(1), one Li(2), one V(1), and one C(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
