Na[GeF₅]·2HF: the first quarternary phase in the H-Na-Ge-F system.

ABSTRACT: The structure of cis- or trans-bridged [GeF₅]^- anionic chains have been investigated [Mallouk et al. (1984). Inorg. Chem. 23, 3160-3166] showing the first crystal structures of μ-F-bridged pentafluorogermanates. Herein, we report the second crystal structure of trans-pentafluorogermanate anions present in the crystal structure of sodium trans-pentafluorogermanate(IV) bis(hydrogen fluoride), Na[GeF₅]·2HF. The crystal structure [orthorhombic Pca2₁, a = 12.3786 (3), b = 7.2189 (2), c = 11.4969 (3) Å and Z = 8] is built up from infinite chains of trans-linked [GeF₆]^2- octahedra, extending along the b axis and spanning a network of pentagonal bipyramidal distorted Na-centred polyhedra. These [NaF₇] polyhedra are linked
