Syntheses, crystal structures, and catalytic activities of three new Cu(II) coordination polymers based on 2-(1H-1,2,4-triazole)-1-acetic acid

Abstract

Three new coordination polymers, {[Cu(trza)(2,2′-bipy)(H₂O)] · (ClO₄)} _n (1), {[Cu(trza)(2,2′-bipy)(H₂O)] · (BF₄)} _n (2), and {[Cu(trza)(4,4′-bipy)] · (H₂O) · (ClO₄)} _n (3) (Htrza = 2-(1H-1,2,4-triazole)-1-acetic acid), have been synthesized and characterized by single-crystal X-ray diffraction analysis. Both 1 and 2 exhibit 1-D chain structure while 3 displays 2-D layer structure. The catalytic activities of 1 and 3 in the green oxidative coupling of 2,6-dimethylphenol have been investigated.
