Synthesis, Crystal Structure, and Luminescent Property of One-Dimensional Chain Coordination Polymer [Cu(1,6-nds)(py)(4)](n)center dot 2.5nH(2)O

摘要

The copper coordination polymer [Cu(1,6-nds)(py)(4)](n)2.5nH(2)O (1,6-nds = 1,6-naphthalenedisulfonate anion, py = pyridine) was synthesized in water by the reflux method. The characterization results of X-ray single crystal diffraction show that the coordination polymer has a one-dimensional chain structure, the two sulfonate groups of 1,6-naphthalenedisulfonate anion bridge with two copper ions by coordination bonds. The copper ion also coordinates with four pyridine molecules. The uncoordinated water molecules interconnect with each other, and also connect to the complex molecules via hydrogen bonds. The coordination polymer displays a strong fluorescence emission peak centered at 462nm.
