Abstract
AbstractA new pendant‐armed macrocyclic ligand, L1, bearing four pyridyl pendant groups has been synthesized by N‐alkylation of the tetraazamacrocyclic precursor L with 2‐picolyl chloride hydrochloride. Metal complexes of L1 have been synthesized and characterized by microanalysis, MS‐FAB, conductivity measurements, IR, UV‐Vis, 1H and 13C NMR spectroscopy and magnetic studies. Crystal structures of the ligand L1 as well as of the complexes [Ni2L1](ClO4)4·5CH3CN and [Cu2L1](ClO4)4·4.5CH3CN have been determined by single crystal X‐ray crystallography. The X ray studies show the presence of two metal atoms within the macrocyclic ligand in both metal complexes showing five coordination arrangement for the metal ions.
