摘要
A new 3D terbium(Ⅲ)metal-organic network[Tb(HIMDC)(HCOO)(H_(2)O)]_(n)(complex 1)has been synthesized by Tb^(3+)ions coordinated with 4,5-imidazole dicarboxylic acid(H_(3)IMDC)and formic acid under solvothermal conditions with the mixed solvents of N,N-dimethylformamide(DMF)and H_(2)O.The unambiguous structural determination has been confirmed by single-crystal X-ray diffraction combined with elemental analysis,infrared(IR)spectrum,thermogravimetric analysis(TGA)and powder X-ray diffraction(PXRD).Complex 1crystallizes in orthorhombic Fdd2 space group with a=22.295(2),b=24.097(3),c=6.7256(6)?,V=3613.3?^(3),Z=16,D_(c)=2.765 g/cm^(3),F(000)=2816,μ=7.855 mm^(-1),the final R=0.0173(I≥2σ(I)),w R=0.0416(all data)and GOOF=1.068.In complex 1,the Tb^(3+)ions are connected by HIMDC^(2-)anions into 2D metal-organic layers which are further extended into a three-dimensional(3D)architecture through formic acid functional motif.In addition,complex 1 shows intense and characteristic green luminescence.
