LiMnCO4 crystallizes in the monoclinic P2_1/c space group. Li(1) is bonded to one O(1), one O(2), one O(3), and two equivalent O(4) atoms to form corner-sharing LiO5 trigonal bipyramids. Mn(1) is bonded in a 5-coordinate geometry to one O(1), one O(3), and three equivalent O(2) atoms. C(1) is bonded in a trigonal planar geometry to one O(1), one O(3), and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Li(1), one Mn(1), and one C(1) atom. In the second O site, O(2) is bonded to one Li(1) and three equivalent Mn(1) atoms to form a mixture of corner and edge-sharing OLiMn3 tetrahedra. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to one Li(1), one Mn(1), and one C(1) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to two equivalent Li(1) and one C(1) atom.
