Structure and stability of gaseous fluorine-bridged heterodimers and heteropolymers: (AF) n(MF 3) m, A′F 2MF 3 (A = H, Li, Na, K; M = B, Al, Fe; A′ =Be, Mg, Mn; n,m = 1, 2)

Abstract

Starting from an overview of experimentally identified and quantum chemically calculated gaseous fluoride heterodimers and oligomers, it is the intention of the authors to survey the present knowledge on structures and stabilities of these complexes and to draw some consequences for experimental chemistry. General characteristics of gaseous halogen-bridged complexes are explained in Section 2. The present knowledge on experimentally identified and quantum chemically calculated fluorine-bridged heterocomplexes is summarized in Section 3. Finally, stabilities and structures of fluoroaluminate complexes in the vapour phase are discussed in Section 4. The discussion is focused on fluoroaluminate complexes containing mono-, di-and trivalent cations.
