The title complex[Co(L)2]Cl·4H2O I has been achieved via self-assembly by incorporating cobalt into 2-benzoylpyridine thiosemicarbazonate ligand,and characterized by elemental analysis,infrared spectra,mass spectra and single-crystal X-ray diffraction study.The crystal crystallizes in monoclinic,space group P21/n,with a=10.227(3),b=17.363(4),c=17.459(4)(A),β=100.408(4)°,V=3049.2(13)(A)3,z=4,Mr=677.08,Dc=1.475 g/cm3,μ(MoKα)=0.834 mm-1,F(000)=1400,the final R=0.0747 and wR=0.0896 for 1663 observed reflections with Ⅰ＞2σ(Ⅰ).The complex contains one six-coordinated cobalt ion connected by two thiosemicarbazone ligands which act as a tridentate ligand to coordinate with the center metal atoms via two pyridyl nitrogen atoms,two imine nitrogen atoms and two sulfur atoms giving rise to a mononuclear structure.Hydrogen bonds existing in the complex link the different components to stabilize the crystal structure.The antitumor activity of the title complex Was tested against A549 lung cancer cell line.Complex Ⅰ exhibits antitumor activity.
