| Abstract: | The coordination capability of two pendant-armed azamacrocyclic ligands with cyanoethyl L1and cyanomethyl L2 pendant groups towards cadmium nitrate and perchlorate salts was achieved. All metal complexes were characterized by elemental analysis, LSI-MS, IR, conductivity measurements and 1H NMR spectroscopy. The X-ray crystal structure of the complexes CdL1](NO3)2, CdL1](ClO4)2 · CH3CN, and CdL2](ClO4)2 · 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 L1. |
