| Abstract: | The ligand 1,4-dibenzoyl-3-thiosemicarbazide (DBtsc) forms complexes M(DBtsc-H)(SCN)] M = Mn(II), Co(II) or Zn(II)], M(DBtsc-H)
(SCN)(H2O)] M = Ni(II) or Cu(II)], M(DBtsc-H)Cl] M = Co(II), Ni(II), Cu(II) or Zn(II)] and Mn(DBtsc)Cl2], which have been characterized by elemental analyses, magnetic susceptibility measurements, UV/Vis, IR,1H and13C NMR and FAB mass spectral data. Room temperature ESR spectra of the Mn(II) and Cu(II) complexes yield <g> values, characteristic
of tetrahedral and square planar complexes respectively. DBtsc and its soluble complexes have been screened against several
bacteria, fungi and tumour cell lines. |
