A pyramidal Tin(II) dication and its reactivity studies

Abstract

An acyclic flexible bis(α-iminopyridine) ligand has been employed for the stabilization of chlorostannyliumylidene and a tin(II) dication. The syntheses involve the abstraction of chloride from the tin dichloride precursor using trimethylsilyl trifluoromethane sulfonate. The apically disposed tin(II) dication exhibits electrophilic behaviour and undergoes transmetallation reaction with GeCl2.dioxane resulting in stabilizing the Ge(II) dication. All the compounds have been characterized by NMR techniques and single crystal X-ray crystallography.
