Synthesis, Characterization and Antimicrobial Activities of Some Transition Metal Complexes Containing Two Bidentate (O-O) Monobasic Hydroxy Aldehydes and 2,2′-Bipyridylamine
摘要:
The mixed-ligand complexes of Mn(II), Fe(II), Co(II), Ni(II), Cu(II) and Zn(II) with 2,2'-bipyridylamine and salicylaldehyde or 5-chlorosalicylaldehyde were prepared and characterized on the basis of elemental analyses, magnetic measurements, infrared spectra, electronic spectra and thermogravimetric analyses. The antimicrobial activities of the complexes were tested against bacteria. An octahedral geometry has been assigned to all the prepared complexes.

Complexes of the transition metals with salicylaldehyde (sa1H) or 5-bromosalicylaidehyde (Br-sa1H) in 1:2 molar ratio, have the compositions [M(H2O)(2)(sal)(2)](H2O)-H-. (1) or [M(H2O)(2)(Br-sal)(2)](H2O)-H-. (2), respectively. The Schiff base derived from ethylenediamine and benzaldehyde in 1:1 molar ratio in alcoholic solution yields bis(benzylidene)ethylenediamine (benen). Further reaction of (1) or (2) with benen in alcohol yielded mixed-ligand complexes of the type [M(sal)(2)benen] or [M(Br-sal)(2)benen], respectively. All of these complexes are soluble in ethanol and methanol.

Complexes of transition metals with salicylaldehyde (saIH) or 5-bromosalicylaldehyde (Br-salH) in I : 2 molar ratio, have the compositions [M(H2O)(2)(sal)(2)] . H2O (1) or [M(H2O)(2)(Br-sal)(2)] . H2O (2), respectively. The Schiff base derived from ethylenediamine and acetophenone in I : I molar ratio in alcoholic solution yields his(acetophenone)ethylenediamine (acphen). Further reaction of (1) or (2) with acphen in alcohol yielded mixed-ligand complexes of the type [M(sal)(2)acphen] or [M(Br-sal)(2) acphen], respectively. All of these complexes are Soluble in ethanol and methanol. They were characterized on the basis of elemental analyses, magnetic measurements, infrared spectra, electronic spectra, and thermogravimetric analyses. All of these complexes have been screened for their antimicrobial activity against bacteria] strands using the agar diffusion method.
