The synthesis and tin‐119m Mössbauer spectra of a series of di (4‐substituted phenyl) tin dichloride complexes with nitrogen‐donor ligands

Abstract

Abstract The synthesis and 119m Sn Mössbauer spectra of a series of 12 new and 3 other organotin complexes of general structure (4‐ZC 6 H 4 ) 2 SnCl 2. L 2. (Z = CH 3 , CF 3 , F, Cl, OCH 3 , L 2 =2,2′‐bipyridyl, 1,10‐phenanthroline, 2‐aminomethylpyridine) arereported. A convenient method for the preparation of the intermediate diaryltin(IV) dihalides is given. The complexes fall into two isomeric types with either a trans ‐ or cis ‐[ArSnAr] geometry. For this series 2‐aminomethylpyridine gives exclusively the cis ‐[ArSnAr] geometry in its complexes.
