Abstract
Adducts of N,N'-dimethyl-2,2'-bisimidazole (DMBIm) with diethyl- and d ibutyl-tin(IV) dihalides (Cl, Br) have been isolated and characterized . IR data for [SnR2X2(DMBIm)] compounds are in keeping with a six-coor dinate tin atom with DMBIm acting as a bidentate ligand, whereas in [( SnR2X2)2(DMBIm)] the tin is five-coordinate and DMBIm acts as a bridgi ng ligand. Measurements of conductivity in acetonitrile show the adduc ts to behave as non-ionogens in this solvent. NMR data show them to un dergo dissociation in CDCl3.
