Synthesis, Crystal Structures and Properties of Two Binuclear Supramolecular Complexes Based on Biphenyl-2,2'-dicarboxylic Acid Ligand

摘要

Two novel binuclear metal-organic coordination complexes [Cd2(Hdpa)4(bpy)2] (1), [Dy2(dpa)2(bpy)2(NO3)2-(E2O)2](bpy) (2) (where H2dpa = biphenyl-2,2'-dicarboxylic acid, bpy = 2,2-bipyridine) have been synthesized under hydrothermal conditions and characterized by single crystal X-ray diffraction, spectral method (IR), elemental analysis (EA), powder X-ray diffraction (XRD), electronic spectra (UV-vis), fluorescent in the solid state and thermogravimetric analysis (TGA). Complexes 1-2 crystallizes isomorphously in the Triclinic space group P-1. The π-π stacking interactions and hydrogen-bonds play a vital role in determining the crystal packing and construction of the extended 3-D supramolecular network.
