Abstract

The coordination polymers (CPs) [Zn2(tipm)(1,3-BDC)2] (1) and [Co2(tipm)(1,3-BDC)2]·0.5CH3CN (2·0.5CH3CN) were synthesized by the reactions of Zn(NO3)2 or Co(NO3)2 with tetrakis[4-(1-imidazolyl)phenyl]methane (tipm) and benzene-1,3-dicarboxylic acid (1,3-H2BDC) under solvothermal conditions. Compounds 1 and 2 are isostructural and possess complicated three-dimensional frameworks with the Schläfli symbol (4·72)(62·73·12)(4·62·73). Cobalt ions were incorporated into the Zn-based CP framework 1 during solvothermal crystallization to yield [Zn(2-2x)Co2x(tipm)(1,3-BDC)2]·bH2O (x = 2.4%, b = 0 for 1a, x = 23%, b = 1 for 2a·H2O). Doped CPs 1a and 2a·H2O exhibited greater catalytic photodegradation of the dye rhodamine B (RhB) than the undoped complexes 1 and 2 and many literature examples.
