A series of new mononuclear nickel(II) complexes derived from dicyandiamide (dcda) and Ni(ClO4)2·6H2O in various alcohol solutions was synthesized and characterized. Nucleophilic addition of the alcohol to the nitrile (–CN) group of the dcda was observed in all complexes, yielding [Ni(L-Me)2](ClO4)2 (1), [Ni(L-Et)2](ClO4)2 (2), [Ni(L-nPr-)2](ClO4)2 (3) and [Ni(L-nBu)2](ClO4)2 (4) in methanol, ethanol,...
In this study, two new copper(II) complexes, [Cu(L1)2](ClO4)2 and [Cu(L2)2](ClO4)2 derived from dicyandiamide were synthesized and characterized by the analytical and spectroscopic methods such as elemental analyses, infrared and mass, spectra. The ligands L1 and L2 formed within the course of the complex formation by nucleophilic attach of alcohols to the nitrile group of the ligand in the presence...
