A New 3D Metal-organic Framework with Tetranuclear Cadmium(Ⅱ) Clusters:Synthesis, Structure, and Luminescent Property
摘要:
A unique metal-organic framework[Cd2(L)1.5(μ3-OH)(H2O)2]·2H2O (1, H2L=2,5-dibenzoylterephthalic acid) has been synthesized under hydrothermal conditions, and characterized by single-crystal X-ray diffractions, elemental analyses, IR spectra and fluorescence spectrum. The compound is of triclinic system, space group P1, C33H27CdO14, Mr=870.33, a=12.2939(17), b=12.5135(9), c=13.2046(10) Å, α=115.3190(10), β=96.9140(10), γ=109.7950(10)°, V=1641.6(3) Å3, Z=2, Dc=1.761 g/cm3, F(000)=862, μ(MoKα)=1.366 mm-1, Rint=0.0148, R=0.0240 and wR=0.0639 for 5995 observed reflections with I>2σ(I). X-ray analysis shows that the title complex exhibits a 3D framework with (412·63) topology, in which the tetra-nuclear[Cd4(μ3-OH)2] clusters act as 6-connected nodes, and the L ligands can be simplified to be linear connectors. Moreover, the thermal stability and fluorescence have been studied in detail.
