Abstract

Two novel compounds [Zn(IAA)2(phen) (HIAA=indole-3-acetic acid, phen=1,10-phenanthroline) (1) and [Zn(IAA)2(4,4'-bipy)](4,4'-bipy=4,4'-bipyridine) (2) were synthesized by the reaction of Zn(Ac)2·2H2O or Zn(SO4)·4H2O as a metal source, HIAA as the first ligand and phen or 4,4'-bipy as the second ligand in the system of methanol or the mixed solution of methanol and water at room temperature. They were characterized by elemental analysis, IR spectroscopy, UV-vis spectra and single-crystal X-ray diffraction. Structural analysis shows that the center metal Zn(II) for the compound 1 is four-coordinated, displaying a distorted tetrahedron; the metal center coordinated model for compound 2 is similar to that of 1, in which the structural unit of Zn(IAA)2 was connected by bridging the 4, 4'- bipy ligand to form an infinite 1D chain. In the packing of the compounds, there are some hydrogen bonding interactions and by the hydrogen bonding, 1D and 2D supramolecular structures were formed. Additional, we have studied the fluorescent properties of the two compounds.
