摘要

Reaction of Cu(ClO_4)_2 6H_2O with 1-alkyl-2-(arylazo)imidazole [RaaiR' where R = H(a),Me(b);R' = Me(1),Et(2)] and NaN_3/NH_4SCN(1 :2:2 mole ratio)form mononuclear complexes [Cu(RaaiR')_2(N_3)_2](3,4)and [Cu(RaaiR')_2(SCN)_2].DMF(5,6).The complexes are characterized by elemental,spectral,electrochemical and other physicochemical results.The structures of both the complexes are confirmed by the single crystal X-ray diffraction studies of [Cu(MeaaiEt)_2(N_3)_2](4b)and [Cu(HaaiMe)_2(SCN)_2].DMF(5a).The complexes are reduced to [Cu(RaaiR')_2]~+ by ascorbic acid.However,air oxidation of [Cu(MeaaiEt)_2](ClO_4)in presence of N_3~-/SCN~-produces [Cu(MeaaiEt)_2(N_3/NCS)_2].
