Organotin(IV) Schiff base complexes of the type (L)SnR 2 [where RCH 3 , C 6 H 5 or CH 2 CH 2 CO 2 CH 3 ], (LH)Sn(C 6 H 5 ) 3 and (L)SnCl(CH 2 CH 2 CO 2 CH 3 ) [where LH 2 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, 1 H, 13 C and 119 Sn 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(SO 2 R) and (LH)(C 6 H 5 ) 2 Sn(SO 2 C 6 H 5 ).
