摘要
A novel Zn（Ⅱ） complex, [ZnL2（H2O）4]·H2O（1, HL = 2-（nicotinoyloxy）acetic acid）, was synthesized using Zn（OAc）2·2H2O and 2-（nicotinoyloxy）acetic acid as raw materials. Its structure has been elucidated by elemental analysis, IR and single-crystal X-ray diffraction. The structural analysis revealed that complex 1 crystallizes in triclinic, space group P1 and the Zn（Ⅱ） atom is six-coordinated with two N atoms from two different 2-（nicotinoyloxy）acetate anion ligands and four O atoms from coordinated water molecules. Complex 1 forms a 3D network structure by O–H···O hydrogen bonds. The antitumor activities of 2-（nicotinoyloxy）acetic acid ligand and its Zn（Ⅱ） complex were evaluated against human lung adenocarcinoma A549 cells, human hepatoma SMMC-7721 cells and human colon carcinoma Wi Dr cells.
