| Summary: | In comparison with previous stucture determinations of Li2PtF6, dilithium hexafluoridoplatinate(IV) [Graudejus et al. (2000). Inorg. Chem. 39, 2794–2800; Henkel & Hoppe (1968). Z. Anorg. Allg. Chem. 359, 160–177], the current study revealed the Li atom to be refined with anisotropic displacement parameters, thus allowing for a higher overall precision of the model. Li2PtF6 adopts the trirutile structure type with site symmetries of 2.mm, m.mm, ..m and m.2m for the Li, Pt and the two F sites. The Pt—F distances in the slightly distorted PtF6 octahedron are essentially similar with 1.936 (4) and 1.942 (6) Å, and the equatorial F—Pt—F angles range from 82.2 (2) to 97.8 (2)°. The Li—F distances in the somewhat more distorted LiF6 octahedron are 1.997 (15) and 2.062 (15) Å, with equatorial F—Li—F angles ranging from 76.3 (7) to 99.71 (17)°.
