The reaction of thiazole (Tz) with diorganotin(IV) dihalides yielded compounds of type [SnR₂X₂(Tz)₂] (R = Me, Et, Ph; X - Cl, Br). The structure of dichlorodiphenylbis(thiazole)tin(IV) was determined by X-ray diffraction. The crystals are monoclinic (space group P2₁/c) and consist of discrete trans-SnPh₂Cl₂(Tz)₂ units with the metal atom coordinated to two Cl atoms, two phenyl carbons, and the N atoms of two thiazole rings. Moessbauer and IR spectra suggest similar trans-stereochemistry for the other complexes prepared. The behavior of these compounds in solution was studied by conductimetry and NMR techniques.
