Abstract
In comparison with previous stucture determinations of Li2PtF6, dilithium hexafluoridoplatinate(IV) [Graudejuset 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. Li2PtF6adopts the trirutile structure type with site symmetries of 2.mm,m.mm, ..mandm.2mfor the Li, Pt and the two F sites. The Pt—F distances in the slightly distorted PtF6octahedron 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 LiF6octahedron are 1.997 (15) and 2.062 (15) Å, with equatorial F—Li—F angles ranging from 76.3 (7) to 99.71 (17)°.
