The structure described by LiVP2O7 crystallizes in the monoclinic P2_1/c space group. Li(1) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(7), and two equivalent O(5) atoms. V(1) is bonded to one O(1), one O(2), one O(3), one O(5), one O(6), and one O(7) atom to form VO6 octahedra that share corners with three equivalent P(1)O4 tetrahedra and corners with three equivalent P(2)O4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(2), one O(4), one O(6), and one O(7) atom to form PO4 tetrahedra that share corners with three equivalent V(1)O6 octahedra and  a cornercorner with one P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 45-61°. In the second P site, P(2) is bonded to one O(1), one O(3), one O(4), and one O(5) atom to form PO4 tetrahedra that share corners with three equivalent V(1)O6 octahedra and  a cornercorner with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 40-50°. There are seven inequivalent O sites. In the first O site, O(7) is bonded in a trigonal planar geometry to one Li(1), one V(1), and one P(1) atom. In the second O site, O(1) is bonded in a 3-coordinate geometry to one Li(1), one V(1), and one P(2) atom. In the third O site, O(2) is bonded in a trigonal planar geometry to one Li(1), one V(1), and one P(1) atom. In the fourth O site, O(3) is bonded in a bent 150 degrees geometry to one V(1) and one P(2) atom. In the fifth O site, O(4) is bonded in a bent 120 degrees geometry to one P(1) and one P(2) atom. In the sixth O site, O(5) is bonded in a 4-coordinate geometry to two equivalent Li(1), one V(1), and one P(2) atom. In the seventh O site, O(6) is bonded in a distorted bent 150 degrees geometry to one V(1) and one P(1) atom. is represented by the CIF card [CIF]
