The material described by LiEuW2O8 crystallizes in the monoclinic P2/c space group. Li(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form distorted LiO6 octahedra that share corners with eight equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 39-60°. Eu(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms. W(1) is bonded to one O(2), one O(4), two equivalent O(1), and two equivalent O(3) atoms to form distorted WO6 octahedra that share corners with four equivalent Li(1)O6 octahedra and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 39-60°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Eu(1) and two equivalent W(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Li(1), one Eu(1), and one W(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Li(1) and two equivalent W(1) atoms. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Li(1), one Eu(1), and one W(1) atom. is represented by the CIF card [CIF]
