title: Bis(1-adamantylammonium) hexafluoridogermanate.
abstract: The title compound, (C(10)H(18)N)(2)[GeF(6)], was obtained hydro-thermally from an aqueous solution of GeO(2), H(3)BO(3), NiCl(2), adamantylammonium chloride, butanol and hydro-fluoric acid. The structure consists of discrete bis(1-adamantylammonium) cations lying on crystallographic mirror planes and hexa-fluoridogermanate anions disordered about sites of 2/m point symmetry. In the latter, the Ge atom lies on the site of 2/m symmetry, one F atom lies on the mirror plane and two further F atoms are included in general positions with 50% site occupancy. The cations and anions lie in layers with N-H⋯F hydrogen bonds formed between them.
