An unusual (4,6)-coordinated copper(II) coordination polymer: High efficient degradation of organic dyes under visible light irradiation and electrochemical properties.

A copper(II) coordination polymer {[Cu(itp)(ip)][Cu 4 (OH) 2 (itp)(ip) 3 ]·4H 2 O} n ( 1 ) (itp = 1-imidazol-1-yl-3-(1,2,4-triazol-4-yl)propane, ip = isophthalate) was synthesized and characterized. 1 exhibits an intriguing 2-fold interpenetrating array of (4,6)-coordinated 3D nets of the fsc topological type, which are based on the 4-coordinated single copper(II) and 6-coordinated tetranuclear hydroxy copper(II) [Cu 4 (μ 3 -OH) 2 ] cluster. 1 is a highly efficient and universal photocatalyst for the degradation of the organic dyes methylene blue (MB), rhodamine B (RhB) and methyl orange (MO) under visible light irradiation. Electrochemical performance of 1 was also measured. [ABSTRACT FROM AUTHOR]
