    Notes: The Schiff bases [H2SBSaD], [H2SBVD] and [H2SBND], derived by the condensation of S-benzyldithiocarbazate and salicylaldehyde, 2-hydroxy-3-methoxybenzaldehyde and 2-hydroxy-1-naphthaldehyde respectively, react with diestertin dichlorides, R2SnCl2 [R=—CH2CH2CO2CH3, —CH2CH2CO2C2H5 or —CH2CH2CO2C4H9] in 1:1 molar proportion to yield chlorine-substituted complexes of the type R2Sn(Schiff base), the base being tridentate. The complexes are characterized on the basis of their elemental analyses, IR and 1H NMR spectral studies. The 13C and 119Sn NMR and the tin-carbon coupling constant data reveal the structures of the complexes to be octahedral with trans ester grouping, and bidentate ester linkages. The pentacoordinated complex (CH3)2Sn(SBSaD) was prepared by the reaction of dimethyltin oxide with H2SBSaD in equimolar proportions.

    Organotin(IV) complexes of dibasic tridentate Schiff bases containing ONO donor atomsNCL Communication No. 5406 (1993)

    Notes: Organotin(IV) Schiff base complexes of the type (L)SnR2 [where R=CH3, C6H5 or CH2CH2CO2 CH3], (LH)Sn(C6H5)3 and (L)SnCl(CH2CH2CO2 CH3) [where LH2=2-N-salicylideneimino-2-methyl-1-propanol, derived from the condensation of salicylaldehyde and 2-amino-2-methyl-1-propanol] have been prepared and characterized on the basis of their elemental analyses, IR, 1H, 13C and 119Sn NMR studies. In these mononuclear complexes the Schiff base acts either as a dianionic tridentate or as a monobasic bidentate moiety by coordinating through an alkoxy group, an azomethine nitrogen and a phenoxide ion to tin. Sulphur dioxide inserts in the tin-methyl/-phenyl bond in the above Schiff base complexes to give tin-O-sulphinates of formulae (L)RSn(SO2R) and (LH)(C6H5)2Sn(SO2C6H5).
