Li2CrO3 crystallizes in the monoclinic C2/c space group. Li(1) is bonded to two equivalent O(2) and three equivalent O(1) atoms to form LiO5 trigonal bipyramids that share corners with four equivalent Li(1)O5 trigonal bipyramids, corners with four equivalent Cr(1)O5 trigonal bipyramids, edges with two equivalent Cr(1)O5 trigonal bipyramids, and edges with four equivalent Li(1)O5 trigonal bipyramids. Cr(1) is bonded to one O(2) and four equivalent O(1) atoms to form CrO5 trigonal bipyramids that share corners with eight equivalent Li(1)O5 trigonal bipyramids, edges with two equivalent Cr(1)O5 trigonal bipyramids, and edges with four equivalent Li(1)O5 trigonal bipyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Li(1) and two equivalent Cr(1) atoms to form OLi3Cr2 trigonal bipyramids that share corners with four equivalent O(1)Li3Cr2 trigonal bipyramids, corners with four equivalent O(2)Li4Cr trigonal bipyramids, edges with two equivalent O(2)Li4Cr trigonal bipyramids, and edges with four equivalent O(1)Li3Cr2 trigonal bipyramids. In the second O site, O(2) is bonded to four equivalent Li(1) and one Cr(1) atom to form OLi4Cr trigonal bipyramids that share corners with eight equivalent O(1)Li3Cr2 trigonal bipyramids, edges with two equivalent O(2)Li4Cr trigonal bipyramids, and edges with four equivalent O(1)Li3Cr2 trigonal bipyramids.
