Complexes of methylethyltin dichloride with 3‐, 4‐picolines, isoquinoline and benzyl amine, of ethyl(n‐propyl) tin dichloride with pyridine, 3‐picoline and isoquinoline and of n‐propyl (n‐butyl)tin dichloride with isoquinoline, n‐propyl amine and benzyl amine have been prepared and their stoichiometries established from their tin and chlorine contents. I.R. measurements (4000–200 cm −1 ) suggest that in all the hexa‐coordinated complexes of methylethyltin dichloride, the chlorines are in cis‐position. In case of hexa‐coordinated complexes of ethyl(n‐propyl)‐ and n‐propyl (n‐butyl) tin dichlorides, however, the multiple splitting of tin‐chlorine stretching band may also be due to the presence of conformational isomers. The conductance measurements have also been carried out to determine their ionic character.
