Assembly of InCl3 with 1,3,5-benzenetricarboxylic acid (H3btc) and pyridine or pyridine derivatives under hydrothermal conditions produces a series of isostructural coordination polymers with the interesting frameworks: {(HL)[In4(OH)4(btc)3]·L·3H2O}n, L=pyridine (1); L=2-picoline (2); L=4-picoline (3) and {(Hdpea)[In4(OH)4(btc)3]·3H2O}n (4) (dpea=1,2-di(4-pyridyl)ethane). In these four complexes, carboxyl and hydroxyl oxygen atoms bridge indium(III) centers to form octahedral chain-like sinusoidal curves, which are further interlinked by btc3− moieties to generate 3-D frameworks with 1-D channels. The protonated guests HL in 1–3 located at the channels can be fully exchanged by K+ ion or partially exchanged by Sr2+, and Ba2+ ions.
Four In(III)-btc isostructural polymers with 3-D channel frameworks formed from octahedral chain-like sinusoidal curves and layers interlinking. The guests pyridine and its derivatives at channels can be exchanged by K+, Sr2+ and Ba2+ ions.Figure optionsDownload as PowerPoint slide
