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)Co_2x(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.
