Two new complexes, [Cu(DMB)2(NAA)2](1) and [Co(DMB)2(NAA)2](2)(DMB = 5,6-dimethylbenzimidazole, HNNA = 1-naphthylacetic acid), were hydrothermally synthesized and characterized by elemental analysis, IR ...Two new complexes, [Cu(DMB)2(NAA)2](1) and [Co(DMB)2(NAA)2](2)(DMB = 5,6-dimethylbenzimidazole, HNNA = 1-naphthylacetic acid), were hydrothermally synthesized and characterized by elemental analysis, IR spectroscopy, TGA, PXRD and single-crystal X-ray diffraction analysis. The coordination geometry of the metal centers is a perfect square plane for 1 and a distorted tetrahedron for 2. In compound 1, the mononuclear units are linked by N–H···O hydrogen bonds to form a 1D chain structure, while mononuclear motifs of 2 are extended via N–H···O hydrogen bonding and π-π stacking interactions into a 2D supramolecular layer. The remarkable catalytic properties of the two complexes for the degradation of Congo red dye have been found.展开更多
