Diethylenetriaminium hexafluoridotitanate(IV) fluoride

Abstract

The title compound, (C6H21N4)[TiF6]F, was synthesized by the reaction of TiO2, tris(2-aminoethyl)amine, HF and ethanol at 463 K in a microwave oven. The crystal structure consists of two crystallographically independent [TiF6]2− anions, two fluoride anions and two triply-protonated tris(2-aminoethyl)amine cations. The Ti atoms are coordinated by six F atoms within slightly distorted octahedra. The anions and cations are connected by intermolecular N—H...F hydrogen bonds.
