Seven new frameworks [Co3(tib)2(BPT)2(H2O)2]·DMA·2.5H2O (1), [Co3(tib)2(BPT)2(H2O)2]·DMF·3H2O (2), [Ni3(tib)2(BPT)2(H2O)2]·DMF·1.5H2O (3), [Ni3(tib)2(BPT)2(H2O)6]·2H2O (4), [Mn(tib)(H2O)3]·HBPT·DMF·2H2O (5), [Ni3(tib)2(BTB)2(H2O)2]·14H2O (6), and [Co3(tib)2(BTB)2]·2DMF·6H2O (7) [tib = 1,3,5-tris(1-imidazolyl)benzene, H3BPT = biphenyl-3,4′,5-tricarboxylic acid, H3BTB = 4,4′,4″-benzene-1,3,5-triyl-tribenzoic acid, DMA = N,N-dimethylacetamide, DMF = N,N-dimethylformamide] were achieved and structurally characterized. 1, 2, and 3 are (3,3,4,4)-connected three-dimensional (3D) frameworks with a point symbol of {83}4{85·12}{86}2, while 4, 6, and 7 are also (3,3,4,4)-connected 3D nets but with different framework structures and topologies. 5 is a two-dimensional network, which is further joined together by hydrogen bonds to generate a 3D supramolecular framework. Gas, vapor, and dye adsorption properties of the frameworks were examined, and 1–7 exhibit hysteretic and selective adsorption of CO2 over N2. Furthermore, 7 is a potential adsorbent for removing methylene blue in the aqueous solution.
