Abstract
A new Cu(II) coordination polymer, namely {[Cu2(btb)2(sip)(OH)]×(H2O)0.25} n (btb = 4,4¢-bis(1,2,4-triazolyl-1-yl)-biphenyl, H3sip = 5-sulfoisophthalic acid), is hydrothermally synthesized and characterized by elemental analyses, infrared (IR) spectroscopy, and single crystal X-ray diffraction. It crystallizes in the monoclinic space group P 21/ c , a = 14.9676(3) Å, b = 14.3478(3) Å, c = 21.2719(5) Å, b = 125.325(2)°, V = 3727.11(14) Å3, Z = 4, C40H28.50Cu2N12O8.25S, M r = 968.39, D c = 1.726 g/cm3, m = 1.274 mm-1. The structural analyses reveal that the compound displays a 2D binodal rarely (4,5)-connected network with 4,5L50 topology. Moreover, the thermal and catalytic properties of the complex for the degradation of the congo red azo dye in a Fenton-like process are investigated.
