摘要：

A new pendant-armed macrocyclic ligand, L-1, bearing four pyridyl pendant groups has been synthesized by N-alkylation of the tetraazamacrocyclic precursor L with 2-picolyl chloride hydrochloride. Metal completes of L-1 hate been synthesized and characterized by microanalysis. MS-FAB, conductivity measurements. IR. UV-Vis, H-1 and C-13 NMR spectroscopy and magnetic studies. Crystal structures of the ligand L-1 as well as of the complexes [Ni2L1](ClO)(4)(.)5CH(3)CN and [Cu2L1](ClO4)(4)(.)4.5CH(3)CN 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.
