Woods 2 Department of Pure and Industrial Chemistry, Nnamdi Azikiwe Universtiy, Awaka (Nigeria) Department of Chemistry University of Ibadan, (Nigeria) <p style="text-align: justify;">Copper (II) complexes of pyridine and picoline were characterized by infrared spectroscopy, ultraviolet spectroscopy, conductivity measurement, solubility test and melting points. The molar conductivity of the complexes in nitromethane revealed that none of the complexes was an electrolyte. The solubility test also showed that all the complexes were insoluble in petroleum ether but sparingly or soluble to some extent in methanol, ethanol methylenedichloride nitromethane and distilled water.</p> https://journalofchemistry.org/paper/623/ copper complexes pyridine picolin and characteristics
