The complex was characterized by single-crystal X-ray diffraction, elemental analysis, IR spectra and TG-DTG techniques. The results show that the crystal is of triclinic, space group P1 with a = 10.912（2）, b = 11.962（3）, c = 12.474（3） A, α = 104.889（3）, β = 93.523（3）, γ = 113.332（3）^o, C66H46Ce2N4O12, Mr = 1366.90, V= 1420.2（6） ,A^3, Z = 1, Dc = 1.598 g/cm^3, μ = 1.652 mm^-1, S = 1.024 and F（000） = 682. The final R = 0.0391 and wR = 0.0947 for 4878 observed reflections with I 〉 2σ（I）. The structure of the title complex consists of two Ce（C6HsCOO）3（C12H8N2） units, forming a binuclear molecule. Each Ce（Ⅲ） is coordinated by two O atoms of one bidentate chelating carboxylate group, five O atoms of two bidentate bridging and two tridentate chelating-bridging carboxylate groups, and two N atoms of one 1,10-phenanthroline molecule to complete a distorted monocapped square antiprism geometry. Its thermogravimetric analysis was determined by TG-DTG techniques.展开更多

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.展开更多

In the crystal the manganese atom is five-coordinated by two chelated nitrogen atoms from phenanthroline, three oxygen atoms from two benzoates and one water molecule, completing a triangular bipyramid geometry. The complex exists in a dimer mode by intermolecular hydrogen-bonding interactions.展开更多
