Syntheses, structures and properties of structural diversity of 3D coordination polymers based on bis(imidazole) and dicarboxylate

Four 3D coordination polymers ([Zn(bib)(ndc)]center dot 0.25H(2)O}(n) (1), [Cd(bix)(bdc)](n) (2), [Cd(bix)(mbda)](n) (3) and [Cu(bix)(0.5)(glu)](n) (4) were synthesized and characterized (bib = 1,4-bis(2-methyl-imidazol-1-yl)butane, bix = 1,4-bis(2-methyl-imidazol-1-methyl)benzene, H(2)ndc = 1,4-naphthalenedicarboxylic acid, H2mbda = 1,3-benzenediacetic acid, H(2)glu = glutaric acid). 1 shows a 4-fold interpenetrating 3D dia network. 2 and 3 exhibit the 4-coordinated self-catenated 3D architecture. 4 exhibits a 6-coordinated self catenated 3D architecture based on [Cu-2(COO)(4)] unit with the paddle wheel structure. The luminescence of 1-3 and thermal stabilities of 1-4 were investigated. 4 is a good photocatalyst for degradation of rhodamine B. (C) 2019 Elsevier Ltd. All rights reserved.
