✦ Synopsis

Organotin(1V) Schiff base complexes of the type (L)SnR2 [where R=CH,, C&15 or CH2CH2C02 CH,] , (LH)Sn( C,H,), and (L)SnCI( CH2CH2C02 CH,) [where LH, = 2-N-salicylideneimino-2methyl-1-propanol, derived from the condensation of salicylaldehyde and 2-amino-2-methyl-lpropanol] have been prepared and characterized on the basis of their elemental analyses, IR, 'H, 13C and '19Sn 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 azumethine 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-0-sulphinates of formulae (L)RSn(S02R) and
