Three indium metal-organic frameworks(In-MOFs), [In(BTB)(2,2?-bipy)]·NMP(1), [In(BTB)(2,2?-bipy)]·NMP·2H_2O(2), and [In(BTB)(NMP)]·0.5NMP(3), have been constructed by the solvothermal reaction of In(NO_3)3·5H_2O and 1,3,5-benzenetribenzoic acid(H3BTB) in similar reaction conditions, and characterized by single-crystal X-ray crystallography, power X-ray diffraction(PXRD), infrared spectroscopy(IR), elemental analysis(EA) and thermogravimetry analysis(TGA). Complex 1 bears a two-dimensional(2D) layered structure of 6,3-connected hcb net topology, and complexes 2 and 3 have 2-fold interpenetrating structures based on 6,3-connected layer, which display the same net topologies with the C_3-symmetric H_3B TB ligands as 3-connected linkers and the In(ⅡI) ions as 6-connected nodes. Moreover, the fluorescent properties of 1~3 have also been studied.
