A hexanuclear CuII-based coordination framework with non-interpenetrated α-Po topology displaying catalytic activity

•A 3D CuII MOF based on metal clusters has been synthesized.•The MOF displays a novel hexanuclear CuII-oxo-cluster.•The complex exhibits high thermal stability.•The complex shows high performance for degradation of congo red.

A 3D six-connected non-interpenetrated α-Po framework with an unique hexanuclear CuII cluster periodically extended by isophthalatlate (ip2 −) and N,N′-(1,1-methyl)-bis(imidazole) (mbim) ligands, [Cu3(μ4-O)(mbim)(ip)2]n (1), has been hydrothermally synthesized and structurally characterized. The complex displays high thermal stability until 285 °C confirmed by thermal analysis and possesses a remarkable catalytic activity for degradation of congo red dye in Fenton process.

Graphical abstractA novel CuII coordination framework has been constructed by isophthalatlate (ip2 −) and N,N′-(1,1-methyl)-bis(imidazole) (mbim) mixed-ligands, which features a non-interpenetrated α-Po topology with unique hexanuclear CuII-oxo-clusters as nodes. The high catalytic property is also found in this complex.Figure optionsDownload full-size imageDownload as PowerPoint slide
