Synthesis, Structure and Luminescent Properties of a Cd(Ⅱ) Coordination Compound

Abstract

Abstract: Cadmium complexes are widely used in the fields of optics, medicine, chemistry and so on because of their unique structure and properties.Hydrothermal method is one of the most convenient and effective methods to synthesize complex at present because of its solvent cleaning and simple operation. A compound [Cd₂(L)₂(bdc)(H₂O)₄](bdc) was hydrothermally synthesized using 2,6-di(pyrazin-2-yl)-4,4′-bipyridine(L), terephthalic acid and CdCl₂·2.5H₂O as raw materials, the structure and luminescent properties of the complexes were characterized by single crystal X-ray diffraction and infrared spectroscopy. The experimental results show that the [Cd₂(L)₂(bdc)(H₂O)₄](bdc) belongs to the triclinic system, P1 space group, a=1.002 78(17) nm, b=1.044 25(17) nm, c=1.274 8(2) nm, β=78.559(2)°, and has good fluorescence.

Key words: cadmium, complex, hydrothermal method, crystal structure, luminescent property
