Abstract
Abstract By using flexible tricarboxylate 4,4′,4″-(((2,4,6-trimethylbenzene-1,3,5-triyl)tris(methylene))tris(oxy))tribenzoic acid (H 3 L) and multiimidazole 1,3,5-tri(imidazo-1-ylmethyl)-2,4,6-trimethylbenzene (titb) ligands simultaneously, three novel coordination polymers [M 3 L 2 (titb) 2 ]·2H 2 O·2.5DMF (M = Co, 1 ; Zn, 2 ; Cd, 3 ) were synthesized under solvothermal conditions and characterized by single-crystal X-ray diffraction, thermogravimetric and photoluminescent studies. The three compounds are isomorphous and possess a three-dimensional (3D) framework built from 2D sheets of L 3− ligands and M ions, and 1D chains of titb ligands and M ions. Topological analyses showed that they exhibit a novel (3,3,4,4) four-nodal 3D net constructed from two 4-connecting metal, and two 3-connecting L 3− and titb nodes. Compounds 2 and 3 are photoluminescent upon excitation at room temperature.
