Zn(II)-azide complexes of diimine and azoimine functions: Synthesis, spectra and X-ray structures
摘要:
Two new series of Zn(II) complexes of alpha/beta-naphthyl-(2-pyridylmethylene)amine and 1-alkyl-2-(naphthyl-alpha/beta-azo)imidazoles with N-3(-) as a counter ion are described in this article. The single crystal X-ray structure of [Zn(beta-naphthyl-(2-pyridylmethylene)amine)(N-3)(2)](2) has revealed an end-on azido bridged dimer while [Zn(1-ethyl-2-(naphthyl-beta-azo)imidazole)(2)(N-3)(2)] is a monomer. The complexes are spectroscopically characterized. Examination of luminescence properties of the complexes suggests that the Schiff bases are emissive and the naphthylazo compounds are non-emissive.
