摘要
The coordination capability of two pendant-armed azamacrocyclic ligands with cyanoethyl L-1 and cyanomethyl L-2 pendant groups towards cadmium nitrate and perchlorate salts was achieved. All metal complexes were characterized by elemental analysis, LSI-MS, IR, conductivity measurements and H-1 NMR spectroscopy. The X-ray crystal structure of the complexes [CdL1](NO3)(2), [CdL1](ClO4)(2)center dot CH3CN, and [CdL2](ClO4)(2)center dot H2O were also determined. All the complexes are mononuclear with the metal ion in a distorted octahedral environment. The pendant groups are not coordinated to the metal due the linear nature of the cyano groups: however, different interactions between nitrate ions, nitrile groups and pyridine rings from the macrocycle have been observed in the Cd(II) complexes with L-1.
