摘要

A new 3D terbium(Ⅲ) metal-organic network[Tb(HIMDC)(HCOO)(H2O)]n (complex 1) has been synthesized by Tb3+ ions coordinated with 4,5-imidazole dicarboxylic acid (H3IMDC) and formic acid under solvothermal conditions with the mixed solvents of N,N-dimethylformamide (DMF) and H2O.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 1 crystallizes in orthorhombic Fdd2 space group with a =22.295(2),b =24.097(3),c =6.7256(6) (A),V =3613.3 (A)3,Z =16,Dc =2.765 g/cm3,F(000) =2816,μ =7.855 mm-1,the final R =0.0173 (Ⅰ ≥ 2σ(Ⅰ)),wR =0.0416 (all data)and GOOF =1.068.In complex 1,the Tb3+ ions are connected by HIMDC2-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.
