Complexes of Co(II), Ni(II) and Cu(II) with a Bidentate Schiff Base and Some Nitrogen Donor Neutral Ligands

Abstract

Complexes of the type [MLL´₂X₂] where M = Co(II), Ni(II),

Cu(II); L = m-nitrobenzaldehyde semicarbazone (MNBS); L´ = pyridine

(Py), γ-picoline (γ-Pic) and quinoline (Qn) X = Cl^–·Br^– and

NO^–₃ were synthesized. The infrared spectra indicate the coordination

of both the ligands to metal ion. Magnetic moment and electronic

spectral data provide existence of octahedral geometry in all

the complexes.
