چکیده

Some new coordination compounds of tin(IV) having general formula [SnBu2 (L)2 ] (where L = carbohydrazone ligand) have been synthesized by the reaction of dibutyltin oxide with carbohydrazone ligands with the ratio of 1:2 (metal- ligand) using dry benzene as a reaction medium. The newly synthesized complexes were characterized by elemental analysis, molecular weight determinations, conductivity measurement and spectral analysis viz., IR, UV-Vis and NMR (1 H, 13C and 119Sn). A distorted octahedral geometry of these complexes has been assigned on the basis of spectral studies. The biological activities of carbohydrazones and their Sn(IV) complexes have been screened in vitro against some bacterial and fungal strain to assess their growth inhibitory potency. Most of the metal complexes exhibit more antibacterial and antifungal activities than the free carbohydrazone ligands against these organisms.
