The structure described by Li2Nb2W2O13 crystallizes in the orthorhombic Imm2 space group. Li(1) is bonded in a 4-coordinate geometry to one O(3), one O(7), and two equivalent O(4) atoms. Nb(1) is bonded to one O(3), one O(6), two equivalent O(1), and two equivalent O(4) atoms to form NbO6 octahedra that share corners with two equivalent Nb(1)O6 octahedra and corners with four equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 30-56°. W(1) is bonded to one O(2), one O(5), two equivalent O(1), and two equivalent O(4) atoms to form WO6 octahedra that share corners with two equivalent W(1)O6 octahedra and corners with four equivalent Nb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 29-41°. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Nb(1) and one W(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms. In the third O site, O(3) is bonded in a tetrahedral geometry to two equivalent Li(1) and two equivalent Nb(1) atoms. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Li(1), one Nb(1), and one W(1) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms. In the sixth O site, O(6) is bonded in a bent 150 degrees geometry to two equivalent Nb(1) atoms. In the seventh O site, O(7) is bonded in a bent 150 degrees geometry to two equivalent Li(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
