LiMnPO4 crystallizes in the orthorhombic Pnma space group. Li(1) is bonded in a distorted rectangular see-saw-like geometry to one O(1), one O(2), and two equivalent O(3) atoms. Mn(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), and four equivalent O(3) atoms. P(1) is bonded in a tetrahedral geometry to one O(1), one O(2), and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Li(1), one Mn(1), and one P(1) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Li(1), one Mn(1), and one P(1) atom. In the third O site, O(3) is bonded to one Li(1), two equivalent Mn(1), and one P(1) atom to form a mixture of distorted corner and face-sharing OLiMn2P trigonal pyramids.
