Abstract

A series of cationic complexes involving a pnictogen(III) (Pn = P, As, Sb) centre and the tetradentate ligand tris((1-ethyl-benzoimidazol-2-yl)methyl)amine (BIMEt₃) have been synthesized and comprehensively characterized. Oxidation of [P(BIMEt₃)]³⁺ with XeF₂ provides access to [PF₂(BIMEt₃)]³⁺ representing the first structurally characterized example of a phosphorus(V) centred trication.
