摘　　要：A new rare earth organic complex with a double interleaved structure,namely[Sm(BDC)1.5(DMF)(H2O)]n(H2BDC=1,4-benzenedicarboxylic acid,DMF=N,N΄-dimethyl formamide)was synthesized.The crystal structure is of triclinic,space group P with a=8.6343(6),b=10.1470(5),c=11.2073(6)Å,α=65.495(5),β=71.626(5),γ=78.130(5)°,V=844.70(9)Å^(3),C_(15)H_(15)NO_(8)Sm,M_(r)=487.64,Z=2,D_(c)=1.917 g/cm^(3),F(000)=476,μ=3.519 mm^(-1),R=0.0380 and wR=0.0864 for 3504 observed reflections(I>2s(I)).The structure has been determined by single-crystal X-ray diffraction analyses and displays a 2-fold interpenetrated 3D network with the classical pcu topology.The compound was analyzed by X-ray powder,infrared spectroscopy,thermogravimetric analysis and fluorescent spectroscopy.The fluorescent property makes it a good candidate for photoactive materials.
