| Summary: | <p>Three bidentate Schiff bases having nitrogen and sulphur donor sequences were prepared by condensing S-benzyldithiocarbazate (<mml:math alttext="chem{NH_2NHCS_2CH_2C_6H_5}"> <mml:msub> <mml:mtext>NH</mml:mtext> <mml:mn>2</mml:mn> </mml:msub> <mml:msub> <mml:mtext>NHCS</mml:mtext> <mml:mn>2</mml:mn> </mml:msub> <mml:msub> <mml:mtext>CH</mml:mtext> <mml:mn>2</mml:mn> </mml:msub> <mml:msub> <mml:mtext>C</mml:mtext> <mml:mn>6</mml:mn> </mml:msub> <mml:msub> <mml:mtext>H</mml:mtext> <mml:mn>5</mml:mn> </mml:msub> </mml:math>) with heterocyclic aldehydes. The reaction of diphenyltin dichloride with Schiff bases leads to the formation of a new series of organotin(IV) complexes. An attempt has been made to prove their structures on the basis of elemental analyses, conductance measurements, molecular weights determinations, UV, infrared, and multinuclear magnetic resonance (<mml:math alttext="chem{^{1}H}"> <mml:mmultiscripts> <mml:mtext>H</mml:mtext> <mml:mprescripts/> <mml:none/> <mml:mn>1</mml:mn> </mml:mmultiscripts> </mml:math>, <mml:math alttext="chem{^{13}C}"> <mml:mmultiscripts> <mml:mtext>C</mml:mtext> <mml:mprescripts/> <mml:none/> <mml:mrow> <mml:mn>13</mml:mn> </mml:mrow> </mml:mmultiscripts> </mml:math>, and <mml:math alttext="chem{^{119}Sn}"> <mml:mmultiscripts> <mml:mtext>S</mml:mtext> <mml:mprescripts/> <mml:none/> <mml:mrow> <mml:mn>119</mml:mn> </mml:mrow> </mml:mmultiscripts> <mml:mtext>n</mml:mtext> </mml:math>) spectral studies. Organotin(IV) complexes were five- and six-coordinate. Schiff bases and their corresponding organotin complexes have also been screened for their antibacterial and antifungal activities and found to be quite active in this respect.</p> |
