Synthesis,Crystal Structure and Antitumor Activity in Vitro of a New Benzoate Binuclear Cupper( Ⅱ) Complex 总被引:3,自引:0,他引:3
The title compound, [Cu2(C7H5O2)4(C2H6O)2], was synthesized by the reaction of benzoic acid, copper acetate and ethanol in an aqueous solution. Trypan blue dye exclusion method was used in experiment. X-ray single-crystal analysis has revealed that compound 1 (C32H32Cu2O10) crystallizes in the monoclinic system, space group C2/c, Mr = 703.66, a = 47.340(5), b = 6.6613(4), c = 22.028(2)A,β = 113.284(4)°, V = 6380.6(10) A^3, Z = 8, Dc= 1.465 g/cm^3, F(000) = 2896,μ = 1.388 mm^-11, the final R = 0.0515 and wR = 0.1172 for 5712 observed reflections with I 〉 2σ(I). X-ray crystal structure analysis suggests that compound [CH2(C7H5O2)4(C2H6O)2] has a binuclear structure with two Cu(II) atoms coordinated by four benzoate groups and two ethanol molecules. The crystal packing is stabilized by intermolecular O-H...O hydrogen bonds. The compound inhibits the proliferation of K562 cells (chronic myeloid leukemic cells) significantly and dose-dependently in 48 h, and IC50 of K562 is 17.3μg/mL by trypan blue dye exclusion method. 相似文献
