Studies on chromium(III) complexes with active nitrogen, oxygen and sulfur donor ketimines synthesized under microwave conditions

Heterocyclic ketimines, 1-(2-furanyl)ethanonehydrazincarbothioamide (L 1H), 1-(2-furanyl)ethanone- hydrazincarboxamide (L2H), 1-(2-thienyl)ethanone hydrazincarbothioamide (L3H) and 1-(2-thienyl) ethanonehydrazincarboxamide (L4H), were prepared by the condensation of thiosemicarbazide and semicarbazide hydrochloride (in the presence of sodium acetate) in ethanol with the respective ketones by using microwave as well as conventional methods. Chromium(III) complexes have been prepared by mixing CrCl3 6H2O in 1:1 and 1:2 molar ratios with monobasic bidentate ketimines. The authenticity of the ligands and their complexes has been established by elemental analyses, melting point determinations, molecular weight determinations, EPR, infrared and UV spectral and X-ray powder diffraction studies. These studies showed that the ligands coordinated to the metal atom in a monobasic bidentate mode, coordinating through the nitrogen and sulfur/oxygen donor system. Thus, an octahedral environment around the metal atoms has been proposed. The growth-inhibiting potential of the ligands and complexes has been assessed against a variety of fungal and bacterial strains.

Microwave assisted synthesis, characterization and antimicrobial studies of unsymmetric imine complexes of organotitanium(IV) and organozirconium(IV)

A new class of uasymmetrical organotitaniuim(IV) and organozirconium(IV) complexes of biologically potent iigands derived from heterocyclic ketones and semicarbazide hydrochloride and 2-hydroxy-N-pheny) benzamide have been prepared by the microwave irradiations. The ligands act in monobasic bidentate manner with N∩OH and O∩OH as donor systems. The ligands and the resulting complexes of the type Cp2M(O∩O) (N∩O) (where M represents titanium or zirconium) are characterized by the elemental analysis, conductance measurements, molecular weight determinations and spectral studies. On the basis of the electronic, IR, 1H NMR and 13C NMR spectral studies, octahedral geometry has been proposed for the resulting complexes. The isolated products are coloured solids, soluble in methanol, DMF, DMSO and THF. A comparative study has been made between microwave assisted synthesis and the thermal synthesis. All the complexes and their parent ligands have been screened against a number of microbes and discussed with positive findings.

Biocidal and antifertility activities of organotitanium and organozirconium complexes derived from nitrogen and sulphur/oxygen donor ligands

A new class of unsymmetrical organotitanium(IV) and organozirconium(IV) complexes of biologically potent ligands derived from heterocyclic ketones and semicarbazide hydrochloride/thiosemicarbazide have been prepared and characterized on the basis of IR and 1H NMR spectral studies and elemental analysis, conductance measurement and molecular weight determinations. The ligands act as monobasic bidentate with NOH and NSH as donor systems. All the organotitanium(IV) and organozirconium(IV) complexes and their parent ligands have been screened against a number of microbes and their sterilizing power on male rat has been tested and discussed with positive findings.
