Assembly of InCl{sub 3} with 1,3,5-benzenetricarboxylic acid (H{sub 3}btc) and pyridine or pyridine derivatives under hydrothermal conditions produces a series of isostructural coordination polymers with the interesting frameworks: {l_brace}(HL)[In{sub 4}(OH){sub 4}(btc){sub 3}].L.3H{sub 2}O{r_brace} {sub n} {sub ,} L=pyridine (1); L=2-picoline (2); L=4-picoline (3) and {l_brace}(Hdpea)[In{sub 4}(OH){sub 4}(btc){sub 3}].3H{sub 2}O{r_brace} {sub 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 btc{sup 3-} 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{sup +} ion or partially exchanged by Sr{sup 2+}, and Ba{sup 2+} ions.
