Synthesis, Spectroscopic and Biological Studies of Some New Binuclear Thiocyanate Complexes Containing Bidentate Schiff Base Ligands

Mouayed Yousif Kadhum, Suhad Rajab Kareem, Sanaa Qasem Badr

Abstract: Two new Schiff bases were synthesized from condensation of 4-nitro benzene diamine with aromatic aldehydes (4-nitro benzaldehyde and 4-hydroxy benzaldehyde). These Schiff bases were reacted with binuclear thiocyanete complexes of MM- (SCN) 4 [M = Co (II), Ni (II), M- = Cd (II)] to produced four new complexes. These compounds were identified by elemental analysis, infrared, Ultraviolet-visible, 1H, 13C-NMR, mass spectra, molar conductance, atomic absorption and magnetic susceptibility. The synthesized Schiff bases were regarded as bidentate ligands and formed complexes of the type LM (NCS) 2M- (SCN) 2. These complexes were non electrolytes and had coordination number equal four. Moreover, these Schiff bases and their complexes were screened for antibacterial and antifungal activity against some microorganisms and compared with standard compounds. It was found that the synthesized compounds had a good antibacterial activity.
