The material structure described by LiTiNiF6 is Hydrophilite-derived structured and crystallizes in the trigonal P321 space group. Li(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form LiF6 octahedra that share corners with two equivalent Ni(1)F6 octahedra, corners with six equivalent Ti(1)F6 octahedra, and edges with two equivalent Ni(2)F6 octahedra. The corner-sharing octahedral tilt angles range from 46-56°. Ti(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form TiF6 octahedra that share corners with four equivalent Ni(2)F6 octahedra, corners with six equivalent Li(1)F6 octahedra, and  an edgeedge with one Ni(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 45-51°. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded to six equivalent F(2) atoms to form NiF6 octahedra that share corners with six equivalent Li(1)F6 octahedra and edges with three equivalent Ti(1)F6 octahedra. The corner-sharing octahedral tilt angles are 56°. In the second Ni site, Ni(2) is bonded to three equivalent F(1) and three equivalent F(3) atoms to form NiF6 octahedra that share corners with six equivalent Ti(1)F6 octahedra and edges with three equivalent Li(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 45-51°. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted trigonal planar geometry to one Li(1), one Ti(1), and one Ni(2) atom. In the second F site, F(2) is bonded in a distorted trigonal planar geometry to one Li(1), one Ti(1), and one Ni(1) atom. In the third F site, F(3) is bonded in a distorted T-shaped geometry to one Li(1), one Ti(1), and one Ni(2) atom. is represented by the CIF file [CIF]
