Spectroscopic and X-ray studies of N-methylanabasine complexes with ZnX2 (X = Br, Cl)

ZnX2 (X = Br, Cl) complexes with N-methylanabasine have been synthesized and characterized by elemental analysis and spectroscopic techniques. The complexes are formulated as [(C11H16N2)2ZnBr2] (1) and [(C11H16N2)2ZnCl2] (2) where C11H16N2 = N-methylanabasine. The X-ray structure of compound 1 is presented. It constitutes the first report on the crystal structure of the metal complex with anabasine or its derivative acting as a ligand. It shows that two N-methylanabasine units and two bromide anions form a tetrahedral coordination around the Zn2+ cation.
