The equilibrium constant of adduct formation between some triorganotin chloride of the type R3SnCl (R=C6H5, p-CH3C6H4, n-CH3)CH2)3, C6H5-CH2 and Lewis bases Cl¯, Br¯, and I¯, were measured in 50% v/v ethanol-water solvent spectrophotometrically. The average equilibrium constant values for the systems studied shows the following acceptor trend of tin(IV) in the triorganotin chlorides: p-tolyl > n-butyl > Phenyl > benzyl The influence of the organic moieties on the acceptor property of tin(IV) is discussed..
