The self-assembly of InCl{sub 3} with 1,4-phenylenediacetic acid (1,4-H{sub 2}pda), 1,3-benzendicarboxylic acid (1,3-H{sub 2}bdc) and 1,4-cyclohexanedicarboxylic acid (1,4- H{sub 2}chdc) generates three new In(III) MOFs, (Me{sub 2}NH{sub 2})[In(cis-1,4-pda){sub 2}] (1), HIn(1,3-bdc){sub 2}{center_dot}2DMF (2) and In(OH)(trans-1,4-chdc) (3) (Me{sub 2}NH=dimethylamine, DMF=N, N'-dimethylformamide). Compound 1 displays a novel 1D no-planar double chain. Although a mixture of cis- and trans-1,4-H{sub 2}pda was used, the product of compound 1 is a single phase with only cis-pda{sup 2-} ligands. Compound 2 possesses a 2D square lattice with sql topology. Interestingly, in compound 2, the 4-connected building unit containing InO{sub 6} octahedron is firstly occurred in In-MOFs. Compound 3 is built up from the infinite metal-oxide chains cross-linked by trans-1,4-chdc{sup 2-} to form 3D framework with rhombus-shaped channels. Furthermore, compounds 1-3 present intense solid-state fluorescent emissions at room temperature. - Graphical abstract: Three new In-MOFs based on different dicaboxylate acids display 1D chain, 2D layer and 3D open-framework, respectively and show strong luminescence emissions at room temperature. Highlights: Black-Right-Pointing-Pointer Three new indium metal-organic frameworks have been solvothermal synthesized. Black-Right-Pointing-Pointer The structural variation is attributed to the diverse coordination modes of ligands. Black-Right-Pointing-Pointer Compounds 1-3 exhibit 1D double chain, 2D layer and 3D open-framework, respectively. Black-Right-Pointing-Pointer These compounds exhibit strong solid-state luminescence emission at room temperature.
