摘要

Two copper(Ⅱ)coordination polymers{[Cu(bib)(nip)]·1.5H2O}n(1)and[Cu2(bib)(glu)2]n(2)(bib= 1,4-bis(2-methyl-imidazol-1-yl)butane,H2nip = 5-nitroisophthalic acid,H2glu = glutaric acid)were synthesized by the hydrothermal method and characterized by single-crystal X-ray diffraction,elemental analyses,1R and solid-state diffuse-reflection spectra.1 forms a 2D network with the point symbol of(44·62)and 2D → 2D polythreaded network.2 constructs the 6-connected 3D network based on the[Cu2(COO)2]dimer with the point symbol of(44·610·8).The energy band gaps(Eg)of 1 and 2 were 2.453 and 2.162 eV,respectively.1 and 2 present high photocatalytic activity for the degradation of methylene blue under visible light irradiation.
