Construction of a novel Cd(II) coordination polymer based on a flexible tripodal carboxylic acid and bimid coligands

A new coordination polymer was solvothermally prepared based on a semi-rigid multidentate carboxylic acid ligand and benzimidazole (bimid) ligand (H3L = 4,4',4"-(((2,4,6 trimethylbenzene 1,3,5triy1)tris(methViene))tris(oxy))tribenzoic acid): [Cd-2(L) (bimid) (DMF)(2)]center dot(DMF)(3)center dot(H2O)(2) (1). The complex 1 was characterized by single crystal X-ray diffraction, infrared spectroscopy, thermogravimetry measurement, elemental analysis and X-ray powder diffraction. Structure analysis reveals that complex 1 displays a rare doubly -interpenetrating (3, 5)-connected hms network with a point symbol {6(3)){6(9).8}. Moreover, the fluorescence and gas adsorption properties of the compound 1 were also explored. (C) 2017 Elsevier B.V. All rights reserved.
