  Dichloro(ethylenediamine-N,N-di-3-propionato)zinc: Synthesis and crystal structure

  摘要：

  Dichloro(ethylenediamine-N,N-di-3-propionato)zinc (I) has been synthesized for the first time by the reaction between acrylic acid and ethylenediamine coordinated with ZnCl2 in an aqueous medium. Complex I has been characterized by IR, Raman, and H-1,C-13 NMR spectroscopy, mass spectrometry, and elemental analysis. The X-ray diffraction analysis of complex I has also been performed. Crystals are monoclinic, D degrees = 9.7792(4) , b = 9.9805(4) , c = 13.1130(5) , beta = 101.5620(10)A degrees, space group D 2(1)/c, Z = 4, V = 1253.88(9) (3), rho(calc) = 1.804 g/cm(3). The coordination polyhedra of Zn atoms in complex I are slightly distorted {ZnCl2O2} tetrahedra, each of which are built of two chlorine atoms and the carboxyl oxygen atoms of the two propionic groups of two ligand molecules and form a polymeric layer parallel to crystallographic plant (100). Bond lengths are Zn-D 1.970(1) and 1.976(1); Zn-Cl 2.2600(4) and 2.2693(4) . The ligand molecule in complex I has a double betaine structure.

  structures of the final products in solution were obtained from the DFT calculations (B3LYP/6-31G(d)) and experimental 1H NMR data acquired during the course of the reaction. The cytotoxic activity of zinc(II) complexes was tested on human breast cancer cell line MDA-MB-231, human colon cancer cell line HCT-116 and normal human lung fibroblast cell line MRC-5. Both complexes reduced cell viabilities, while

  reacts with [CuCl2(en)], and likely the complex geometry remains square-planar. Kinetic results have shown that the order of reactivity of nucleophiles towards [CuCl2(en)] in solution for both reaction steps is 1,2,4-triazole > imidazole > pyrazine. The order of reactivity of the azole and diazine ligands toward [CuCl2(terpy)] for the first reaction step is imidazole > 1,2,4-triazole > pyrazine, while
