Tornero, J. D. published the artcileMixed halide complexes of tin(IV) with pyridine, Recommanded Product: Pyridine Iodochloride complex, the publication is Anales de Quimica, Serie B: Quimica Inorganica y Quimica Analitica (1986), 82(2), 145-9, database is CAplus.
By oxidative-addition reactions of X2 (X = Br, I) and XI.py (X = Cl, Br) to SnCl2 in the presence of pyridine, SnCl2X2py2 (X = Br, I), SnCl3Ipy2 and SnCl2BrIpy2 were obtained and studied by vibrational and 119Sn Moessbauer spectroscopy. A C2v symmetry, with the ligands in trans positions, was proposed for SnCl2Br2py2, whereas Moessbauer spectra of the remaining species show the presence of some impurities. A linear regression between the position of some pyridine bands in the IR spectra and the average electronegativity of halogens was observed, the υ4 frequency being the most sensitive with respect to the metal-ligand bond strength.
