STUDIES ON THE DIORGANOTIN(IV) COMPLEXES OF SOME DIHYDROXAMIC ACIDS

Twenty-one diorganotin(IV) complexes of N,N-substituted dihydroxamic a cids of the formula {R(2)(1)Sn[ON(R)CO](2)(CH2)(n)}(2)(R(1)=n-C4H9, C6 H5; R=C6H5, 4-CH3C6H4, 4-ClC6H4) were synthesized by the reaction of d iorganotin(IV) dichlorides and dihydroxamic acids in the presence of t riethylamine. Molecular weight determinations and electronic, IR, Rama n and NMR spectroscopic techniques were utilized for the characterizat ion and elucidation of the structural and bonding aspects of the compo unds. The results suggest that all the compounds are dimeric and the d i-n-butyltin(IV) dihydroxamates have trans-octahedral structures, wher eas the diphenyltin(IV) dihydroxamates have cis-octahedral structures.
