摘    要:One dinuclear complex [Cu2Cl2(HEMDP) 2]·THF 1(H2EMDP = 2-[(2-hydroxyethylimino)-methyl]-4,6-diiodo-phenol,THF = tetrahydrofuran) has been designed and synthesized by H2EMDP with CuCl2·2H2O in THF solvent. Complex 1 was characterized by UV,IR,ESI-MS,and elemental analyses. 1 was characterized by X-ray crystallography. The crystal belongs to the monoclinic system,space group C2/c with a = 27.886(3) ,b = 8.6890(12) ,c = 26.698(2) ,β = 105.521(2) o,V = 6233.1(12) 3,Z = 8,Mr = 1102.01,μ = 5.533 mm-1,Dc = 2.349 Mg/m3,F(000) = 4112,the final R = 0.0486 and wR = 0.1175(I > 2σ(I)) . In addition,further investigation revealed that the central copper(Ⅱ) atom in the complex is five-coordinated by one nitrogen atom and two oxygen atoms from H2EMDP and two chlorine atoms from chlorid. The 3,5-diiodosalicylaldehyde Schiff base acts as a tridentate ligand. H2EMDP and 1 were assayed for antibacterial(B. subtilis,S. aureus,S. faecalis,P. aeruginosa,E. coli and E. cloacae) activities by MTT(3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl trtrazolium bromide) method. 1 showed the most favorable antimicrobial activity with MICs of 3.125,6.25,6.25,12.5,3.125 and 6.25 μg/mL against B. subtilis,S. aureus,S. faecalis,P. aeruginosa,E. coli and E.cloacae,respectively.
