Interpenetration of Three 2D In-MOFs with (6,3) Topology: Syntheses, Structures and Fluorescent Properties
摘要:
Three indium metal-organic frameworks (In-MOFs),[In(BTB)(2,2'-bipy)]·NMP (1),[In(BTB)(2,2'-bipy)]·NMP·2H2O (2), and [In(BTB)(NMP)]·0.5NMP (3), have been constructed by the solvothermal reaction of In(NO3)3(OH)2·5H2O 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 C33-symmetric H3BTB 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.
