Abstract: A tetrahedral zinc complex Zn(L)2, L=anionic form of S-p-chlorobenzyl-β-N-(2,4-dichlorobenzylidene)hydrazinecarbodithioate, has been prepared and characterized by elemental analysis, IR and single-crystal X-ray diffraction. The crystal data for the complex: Monoclinic, space group P21/n, a=1.242 6(10) nm, b=1.024 4(11) nm, c=2.840 2(2) nm, β=101.740 0(10)°, Mr=842.81, V=3.539 7(5) nm3, Z=4, μ=1.412 mm-1, Dc=1.582 g·cm-3, F(000)=1 696, R1=0.039 0, wR2=0.086 2 (observed reflections with I>2σ(I)) and R1=0.164 0, wR2=0.099 6 (all reflections), Final GooF=1.015. In the crystal structure, the zinc(Ⅱ) complex has a distorted tetrahedral geometry in which the zinc ion is four-coordinated by the nitrogen atoms and sulfur atoms from two Schiff base ligands respectively. The preliminary bioassay indicates that the zinc complex exhibit distinct inhibitory activity against the human gastric cancer cell lines. CCDC: 829805. |
