Preparation and Characterization of Nicotinium Tetrahalocuprate(II) and Tetrahalocobaltate(II) Complexes : Structure of Nicotinium Tetrachlorocobaltate(II)

摘要

Nicotine (C_(10)H_(14)N_2,nic) is one of the alkaloids well recognized for it's toxin activity,and it's chemistry is an important topic because of its health implications.Nicotine possesses the methylated pyrrolidine nitrogen (pK_(b1) = 6.16) and the less basic pyridine nitrogen (pK_(b2) = 10.96),thus it forms a chelate complex resulting in a CuN_2X_2 chromophore when it reacts with the copper(II) halides.
