Crystal structure and spectroscopic characterization of Zinc(II) and mercury(II) complexes of N-(Pyridin-2-ylmethylene)benzene-1,4-diamine

چکیده مقاله

The behavior of AÎ7V'-bis(pyridin-2-ylmethylene)benzene1,4-diamine (L) towards zinc(II), cadmium(II), and mercury(II) chlorides was studied in methanol solutions. In the presence of metal ions, the organic molecule was decomposed to (pyridin2-ylmethylene)benzene-l,4-diamine (L'), and complexes of general formula M(L')Cl2 were isolated, from the mixture. The complexes were identified by elemental analysis, IR, ¹H NMR, and. ¹³C.NMR spectra, and their structures were further confirmed, by single-crystal X-ray diffraction analysis of Zn(L')Cl₂ and. Hg(L')Cl². In the solid state of both complexes, the molecules are stabilized by N-H*"C1 hydrogen bonds and aromatic JI-Jt stacking interactions. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA,.
