Two new Cu(II) complexes constructed by mixed-organic tectonics: Structures, magnetic properties and photocatalytic degradation of organic dyes

•Two new Cu(II) complexes constructed by mixed-organic tectonics•2D supramolecular network based on binuclear unit•2D undulating network propagated by a 1D looped chain and μ2-bipy pillar•The photocatalytic activity for degradation of rhodamine B (RhB) under visible-light

Two new mixed-ligands Cu(II) complexes, [Cu(hfipbb)(2,2′-bipy)(H2O)2]n (1) and [Cu2(hfipbb)2-(4,4′-bipy)(H2O)]n (2) (H2hfipbb = 4,4′-(hexafluoroisopropylidene)bis(benzoic acid)), were prepared, which both show different 2D networks and the antiferromagnetic interactions between the adjacent Cu(II) ions as well as photocatalytic degradation activity for dye degradation.

Graphical abstractTwo new mixed-ligands Cu(II) complexes [Cu(hfipbb)(2,2′-bipy)(H2O)2]n (1) and [Cu2(hfipbb)2(4,4′-bipy)(H2O)]n (2) present a two-dimensional (2D) supramolecular network and 2D undulating network, respectively. Notably, compounds 1 and 2 exhibit photocatalytic activity for degradation of rhodamine B (RhB) under visible-light.Figure optionsDownload full-size imageDownload as PowerPoint slide
