Metal complexes of general formula [M(L) 2 ]Cl 2 and [Fe(L) 2 Cl 2 ] where M is Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) and L is the Schiff base, 2-(pyrimidin-2-yliminomethyl) furan (FAP) are prepared. The complexes were characterized by analytical as well as spectroscopic, magnetic and conductance measurements. The infrared spectra of the complexes agree with coordination to the central metal atom through the nitrogen of the azomethine group and oxygen of the furan ring. Magnetic susceptibility data coupled with electronic spectra suggest a distorted octahedral structure for the Fe(II) complex, a tetrahedral geometry for the Mn(II), Co(II) and Zn(II) complexes, and a square planar for the Ni(II) and Cu(II) complexes. Conductance measurements suggest the 1 :2 electrolytic nature of the complexes with the exception of the Fe(II) complex as of a non-electrolytic nature.
Metal complexes of general formula [M(L) 2 Cl 2 ] and [Cr(L) 2 Cl 2 ]Cl {where M is Mn(II), Fe(II), Co(II), Ni(II) and Cu(II) and L (2,3-Bis (Nhexylimino) butane) is a Schiff base formed by condensation of 2,3butanedione and hexylamine}, have been prepared (in 1:2 metal: ligand molar ratio). The complexes were characterized by analytical, spectral, magnetic and conductance measurements. IR spectra show that the nitrogen of the azomethine groups takes part in coordination. Magnetic measurements and electronic spectral studies suggest an octahedral structure for all complexes. Conductance measurements show a non electrolytic nature of the complexes, with the exception of the [Cr(L) 2 Cl 2 ]Cl compound with a 1:1 electrolytic nature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
