The material described by LiNaLu2F8 crystallizes in the orthorhombic Cmcm space group. Na(1) is bonded in a 7-coordinate geometry to one F(3), two equivalent F(4), and four equivalent F(2) atoms. Li(1) is bonded to two equivalent F(1) and four equivalent F(2) atoms to form distorted corner-sharing LiF6 octahedra. The corner-sharing octahedral tilt angles are 46°. Lu(1) is bonded in a 8-coordinate geometry to one F(1), one F(3), two equivalent F(4), and four equivalent F(2) atoms. There are four inequivalent F sites. In the first F site, F(1) is bonded to two equivalent Li(1) and two equivalent Lu(1) atoms to form distorted FLi2Lu2 tetrahedra that share corners with two equivalent F(1)Li2Lu2 tetrahedra, corners with eight equivalent F(2)NaLiLu2 trigonal pyramids, and edges with four equivalent F(2)NaLiLu2 trigonal pyramids. In the second F site, F(2) is bonded to one Na(1), one Li(1), and two equivalent Lu(1) atoms to form distorted FNaLiLu2 trigonal pyramids that share corners with two equivalent F(1)Li2Lu2 tetrahedra, corners with six equivalent F(2)NaLiLu2 trigonal pyramids,  an edgeedge with one F(1)Li2Lu2 tetrahedra, and edges with three equivalent F(2)NaLiLu2 trigonal pyramids. In the third F site, F(3) is bonded in a trigonal planar geometry to one Na(1) and two equivalent Lu(1) atoms. In the fourth F site, F(4) is bonded in a distorted T-shaped geometry to one Na(1) and two equivalent Lu(1) atoms. is represented by the CIF card [CIF]
