The crystal structure described by LiSm(WO4)2 is Zircon-derived structured and crystallizes in the tetragonal I-4 space group. Li(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. Sm(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. There are two inequivalent W sites. In the first W site, W(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. In the second W site, W(2) is bonded in a tetrahedral geometry to four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Li(1), one Sm(1), and one W(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Li(1), one Sm(1), and one W(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
