Synthesis, characterisation and biological activity of the complexes of manganese(II), iron(II), cobalt(II), nickel(II), copper(II), zinc(II) and cadmium(II) with N-benzoyl-N'- 2-furanthiocarbohydrazide

Abstract

A new ligand N-benzoyl-N'-2-furanthiocarbohydrazide (H₂Bfth) formed 1:1 deprotonated complexes with Co(II), Ni(II), Cu(II) and Zn(II) while 1:2 deprotonated complexes with Mn(II), Fe(II) and Cd(II). The complexes have been characterized by elemental analyses, magnetic susceptibility measurements, and UV-vis, IR, ESR. NMR (¹H and ¹³C), mass/FAB mass and Mossbauer spectral studies. The biological activity have been screened against several bacteria and fungi.
