Synthesis, Structure and Fluorescence Properties of a Pyrazinyl Carboxylate Cadmium Complex

Abstract

Abstract: Pyrazine compounds are widely used in pharmaceutical, medicine, chemistry and other fields due to their unique structure and activity. Using water as solvent, hydrothermal method is the preferred method for complex synthesis because of its green, pollution-free and simple operate. In this paper, 2,6-bis (2-pyrazinyl) pyridine-4-p-benzoic acid (Hbppc) and CdCl₂·2.5H₂O were used as raw materials, a new coordination compound [Cd(bppc)(H₂O)Cl]_n was synthesized by hydrothermal method, and its structure was characterized by single crystal X-ray diffraction, infrared spectroscopy and Raman spectroscopy. The results show that the complex has a one-dimensional chain structure. The fluorescence analysis of free ligand 2,6-bis (2-pyrazinyl) pyridine-4-p-benzoic acid and its complex [Cd(bppc)(H₂O)Cl]_n show that the obtained complex has good fluorescence property.

Key words: pyrazinyl carboxylate cadmium complex, crystal structure, fluorescence property, hydrothermal method
