The toxicological effects, biological aspects and spectral characterization of organoboron(III) complexes of sulfonamide‐imines derived by the condensation of salicylaldehyde with different sulfa‐drugs are described. The benzene‐soluble, high‐molecular‐weight complexes have been characterized using a wide range of analytical and spectroscopic techniques, viz. UV, IR, 1 H and 11 B NMR. On the basis of these studies, it is inferred that the imines derived from sulfa drugs and salicylaldehyde behave as dibasic tridentate ligands and thus provide a tetrahedral environment around the boron atom. Finally, all these complexes have been screened for their antimicrobial activity against a variety of fungal and bacterial strains and their toxicological effects on male albino rats examined at the dosages employed.
