The material structure described by LiVOPO4 crystallizes in the monoclinic P2_1/c space group. Li(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(4), one O(5), and two equivalent O(3) atoms. V(1) is bonded to one O(1), one O(2), one O(4), one O(5), and two equivalent O(3) atoms to form VO6 octahedra that share corners with four equivalent P(1)O4 tetrahedra and  an edgeedge with one V(1)O6 octahedra. P(1) is bonded to one O(1), one O(2), one O(4), and one O(5) atom to form PO4 tetrahedra that share corners with four equivalent V(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 14-54°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Li(1), one V(1), and one P(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Li(1), one V(1), and one P(1) atom. In the third O site, O(3) is bonded to two equivalent Li(1) and two equivalent V(1) atoms to form distorted edge-sharing OLi2V2 trigonal pyramids. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Li(1), one V(1), and one P(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to one Li(1), one V(1), and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
