Finally, the cytotoxic and antibacterial activities of the oxamido-bridged binuclear complexes were studied in vitro.. This dissertation consists of three sections as follows:1. The crystal structure of a oxamide dinitrate,(1) [H_4dmaeoxd](NO_3)_2 H_2dmaeoxd = N,N\'-bis[2-ethyloxamide, has been obtained. The diversity of complexes with different structures is carried out by successful synthetic strategy of controlling species of metal ions, counter anions, pH values and solvents in the course of synthesis. Four dinuclear complexes bridged by trans-dmaeoxd2-: [Cu_2_2](ClO_4)_2 (2), [Cu_2_2](ClO_4)_2 (3),、[Cu_2(Me_2phen)_2](ClO_4)_2 (4), [Cu_2_2(H_2O)_2] (5); Four dinuclear complexes bridged by cis-dmaeoxd2-: [NiNi_2](ClO_4)_2 (6), [CuNi_2](ClO_4)_2·2CH_3OH (7), [CuZn_2]-(ClO_4)_2·2H_2O (8), [Cu(H_2O)Ni_2](ClO_4)_2.0.5CH_3OH (9); three 1-D polynuclear complexes: [Cu_2]_n·nH_2O (10), [Cu_2(H_2O)_2-]_n·4nH_2O (11), [Cu_2(H_2O)]_n(NO_3)_n·2nH_2O (12); one 2-D polynuclear complex,[Cu_6_3(μ_3-OH)_2(H_2O)_2]_n(ClO_4)_(4n).2nH_2O (13); the others: [VO(H_2O)]·2H_2O (14), [Zn_2_4](ClO_4)_2·H_2O (15), [Cu_2]·2DCM (16) have been synthesized and characterized by X-ray single crystal diffraction, elemental analysis, IR spectra.
