Four new coordination complexes prepared for the degradation of methyl violent dye based on flexible dicarboxylate and different N-donor coligands

Abstract

A ether-bridged dicarboxylic acid, 4,4′-{[1,2-phenylenebis-(methylene)]bis(oxy) dibenzoic acid (H2L), was used as highly versatile building block for the hydrothermal generation of a series of coordination polymeric architectures in thepresence of 1,1′-(1,4-butanediyl)bis(imidazole) (bbi) and 1,10-phenanthroline (phen). These were formulated as [Co2(L)2(bbi)·CH3CN]n (1), [Cu(L)(bbi)]n (2), [Co(L)(phen)(H2O)]n (3), and [Cu(L)(phen)(H2O)·2CH3CN]n (4), have been synthesized and characterized. Thenature of the N-donor building blocks and metal ions have a significant effect on the structural diversity. Photocatalytic properties of selected materials were investigated, showing that 2is a promising photocatalyst for the UV-light-driven degradation of methyl violet (MV) as a model organic dye pollutant.
