Abstract
Two new Cu(II)/Co(II) coordination polymer (CPs) namely, [Co-2(H2O)(2)(L)(2)(2,2'-bipy)(2)center dot H2O] (1) and [Cu-2(L)(2)(bbi)] (2) (H2L= 3,3'-(1,2-phenylenebis(methyleneoxy)) dibenzoic acid, bbi = 1,1'-(1,4-butanediyl)bis(imidazole), 2,2,'-bipy=2,2,'-bipyridine), have been designed and synthesized. 1 has 1D helical structure built by the connectivity of Co atoms and phenolic-oxygen containing branches of the flexible dicarboxylate linkages, which was further form a 2D supramolecular sheet through the strong pi center dot center dot center dot pi stacking interactions and H-bonded interactions. 2 exhibits 2D layer constructed by the double [Cu4L2] chains and anti-conformational bbi ligands. The current results illustrated that the N-donor ligand may play a distinct effect in the formation of these mortifies. The photocatalytic performances to degrade methyl violet (MV) and Rhodamine B (Rh B) under UV irradiation were studied. (C) 2021 Elsevier B.V. All rights reserved.
