Abstract:
A new water-stable metal-organic framework, [Cu2 (bdc)2 (tpt)3]2H2O (1, H2bdc = terephthalic acid, tpt = 2,4,6-Tri(4-pyridinyl)-1,3,5-Triazine), has been synthesized and characterized by elemental analysis, infrared (IR) spectrum, thermogravimetric analysis (TGA), powder X-ray diffraction (PXRD) and single-crystal X-ray diffraction. Compund 1 crystalizes in monoclinic, space group C2/c with a = 30.147(5), b = 11.0548(17), c = 20.867(4) A, β = 115.035(2), C70H48Cu2N18O10, Mr = 1428.34, V = 6301.0(18) A3, Z = 8, Dc = 1.506 g/cm3, μ = 0.754 mm-1, F(000) = 2928, GOOF = 1.058, λ(MoKα) = 0.71073 A, the final R = 0.0387 and wR = 0.1091 for 6230 observed reflections with I < 2δ(I). In compound 1, the half metallacycles [Cu2(tpt)3] are linked by the bdc2-ligands to form a 1D bent ladder-like chain featured with a nano-sized channel, and these chains link each other via intermolecular hydrogen bonds and φ-φ stacking interactions to form a 3D supramolecular architecture with the voids filled with free water molecules. In addition, the water stability of 1 was investigated by PXRD patterns, which indicate that compound 1 keeps its structural integrity in boiling water for at least three days.
