The material structure described by LiSbP2O7 crystallizes in the monoclinic P2_1/c space group. Li(1) is bonded to one O(1), one O(2), one O(3), one O(6), and one O(7) atom to form distorted LiO5 trigonal bipyramids that share corners with three equivalent Sb(1)O6 pentagonal pyramids, corners with two equivalent P(2)O4 tetrahedra, corners with three equivalent P(1)O4 tetrahedra, and  an edgeedge with one Sb(1)O6 pentagonal pyramid. Sb(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 distorted SbO6 pentagonal pyramids that share corners with three equivalent P(1)O4 tetrahedra, corners with three equivalent P(2)O4 tetrahedra, corners with three equivalent Li(1)O5 trigonal bipyramids, and  an edgeedge with one Li(1)O5 trigonal bipyramid. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(2), one O(3), one O(4), and one O(6) atom to form PO4 tetrahedra that share corners with three equivalent Sb(1)O6 pentagonal pyramids,  a cornercorner with one P(2)O4 tetrahedra, and corners with three equivalent Li(1)O5 trigonal bipyramids. In the second P site, P(2) is bonded to one O(1), one O(4), one O(5), and one O(7) atom to form PO4 tetrahedra that share corners with three equivalent Sb(1)O6 pentagonal pyramids,  a cornercorner with one P(1)O4 tetrahedra, and corners with two equivalent Li(1)O5 trigonal bipyramids. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Li(1), one Sb(1), and one P(2) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Li(1), one Sb(1), and one P(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Li(1), one Sb(1), and one P(1) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one P(1) and one P(2) atom. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to one Sb(1) and one P(2) atom. In the sixth O site, O(6) is bonded in a distorted trigonal planar geometry to one Li(1), one Sb(1), and one P(1) atom. In the seventh O site, O(7) is bonded in a 3-coordinate geometry to one Li(1), one Sb(1), and one P(2) atom. is represented by the CIF file [CIF]
