Magnetic and photocatalytic degradation properties of a 2D (3,4) connected framework based on 4,4'-(1'H,VH-2,2'-biimidazole-1,1'diylbis(methylene))dibenzoic acid

摘要

A new Co(II) coordination polymer, namely [Co(L) (1,4-bib)(0.5)(H2O)(2)]n (1) (H2L = 4,4'-(1H,1'H-2,2'-biimidazole-1,1'-diyIbis(methylene))dibenzoic acid, 1,4-bib = 1,4-bis(1-imidazoly)benzene) have been hydrothermally synthesized. The structure of the title complex was determined by single crystal X-ray diffraction analysis and further characterized by infrared spectrum (IR), elemental analysis and UV Vis spectrum. Magnetic investigations reveal that the antiferromagnetic interactions exist between the adjacent Coll ions in complex 1. Moreover, complex 1 have high photocatalytic degradation effects on rhodamine B, methylene blue and methyl orange under UV irradiation. (C) 2017 Elsevier B.V. All rights reserved.
