A three-dimensional metal–organic framework based on a triazine derivative: syntheses, structure analysis, and sorption studiesElectronic supplementary information (ESI) available: Ligand synthesis and characterisation, structural and PXRD data, TGA and hydrogen sorption isotherms. CCDC reference number 721250. For ESI and crystallographic data in CIF or other electronic format see DOI: 10.1039/b903932eSynthesis of 1: A mixture of m-H3TATB (0.01 g, 2.25 × 10−5mol), 0.05 ml pyridine, Cu(NO3)2·2.5H2O (0.050 g, 2.15 × 10−4mol) was dissolved into 1.35 ml dimethyl sulfoxide (DMSO) and 0.15 ml CH3OH in a 15 ml Teflon-lined reactor and heated at a constant rate of 1 °C min−1to 120 °C, kept at that temperature for 2 d, and cooled to room temperature at a constant rate of 0.1 °C min−1. The resulting turquoise block crystals were washed with DMSO (0.010 g, yield: 56%). Elemental analysis (%) calcd for Cu3C61H59N7S3O19: C 47.47, H 4.02, N 6.62; found: C 47.21, H 4.01, N 6.38.Crystal data for 1·3D

A novel metal–organic framework [Cu3(m-TATB)2Py(CH3OH)2] (1) constructed of a triazine-based trigonal-planar ligand, 3,3′,3″-s-triazine-2,4,6-triyltribenzoate (m-H3TATB), has been synthesized and structurally characterized. Compound 1features three-dimensional (3D) channels and cavities together, and exhibits high carbon dioxide sorption at normal pressure. [ABSTRACT FROM AUTHOR]
