Abstract: Abstract The ligand dpamc (2,2’-dipyridylammoniumchloride) has been synthesized from dpa (2,2’-dipyridylamine) and acyl chloride via acylation reaction and characterized on the basis of NMR , UV/Vis and elemental analysis. The Cu (II) complex of this ligand was also synthesized and characterized on the basis of spectral data (UV/Vis, AAS), molar conductance, magnetic susceptibility, and elemental analysis. The complex formed is proposed to have a square planar geometry. The ratio of the ligand to Cu (II) in the complex is 2:1 in which each dpa unit acts as a bidentate ligand, coordinating through both pyridyl nitrogens to form a six-membered chelate ring. The Cu (II) complex is a 1:2 electrolyte implying that there are two chloride ions with a complex. The chloride content in the outer sphere of the complex was determined by treatment with silver nitrate solution and gave a positive result.
