摘要
Four new complexes of the general formula [Co(L-n)Cl] (where L-n is dianion of pentadentate Schiff base ligand N, N'-bis(2-hydroxybenzylidene)-1,6-diamino-3-azahexane = H2L1, N, N'-bis(2-hydroxy-3methoxy- benzylidene)-1,6-diamino-3-azahexane = H2L2, N, N'-bis(3-ethoxy-2-hydroxy-benzylidene)1,6- diamino-3-azahexane = H2L3 or N, N'-bis(2-hydroxybenzylidene)-1,7-diamino-4-methyl-4-azaheptane = H2L4) have been synthesized and characterized by elemental analyses, IR, UV-VIS. The redox properties have been studied by cyclic voltammetry. Moreover, the crystal structures of 1, 2 and 3 have been determined by X-ray diffraction and H-1 NMR spectrum of 4 has been obtained.
