摘要：
Cadmium(II) complexes of N-[(2-pyridyl)methyliden]-alpha (or beta)-aminonaphthalene (alpha or beta-NaiPy) and 1-alkyl-2-(naphthyl-alpha (or beta)-azo)imidazoles (alpha- or beta-NaiR) using Cl-, ClO4- and NO3- as anions are spectroscopically characterized. Molar conductance data in nitromethane show that the chloro and nitrite compounds are non-conducting, while the perchlorate complexes are 1:2 electrolytes. The single crystal X-ray structure of [Cd(N-{(2-pyridyl)methyliden}-beta-aminonaphthalene)(2)(ONO2)(2)] has been determined. The luminescence properties of Cd(II) complexes of alpha/beta-NaiPy are studied and they exhibit ligand centered pi-pi* emissions. Naphthylazoimidazoles and their cadmium complexes are non-fluorescent. (c) 2006 Elsevier Ltd. All rights reserved.
