摘 要: | A new dinuclear Tb(Ⅲ) 4-cyanobenzoate complex [Tb2(4-cba)6(phen)2] (4-Hcba = 4-cyanobenzoic acid and phen = 1,10-phenanthroline) 1 has been synthesized by solvothermal reaction in an ethanol/water mixed solution at 100℃ and structurally characterized by single-crystal X-ray diffraction. Crystallographic data: C72H40N10O12Tb2, Mr=1554.98, triclinic Pi, a = 9.903(3), b = 11.769(8), c = 15.078(8)A, a = 111.42(12), It = 96.37(19), γ = 101-24(14)°, V= 1572(1)A3, Z= 1, Dc = 1.642 g/cm^3, F(000) = 768 μ = 2.305 mm^-1, the final R = 0.0205 and wR = 0.0543 for 5479 reflections with I 〉 2σ(I). Structural analysis shows that 1 displays an isolated dinuclear structure. Two eight-coordinated Tb(Ⅲ) ions are bridged by four 4-cba ligands in the syn-syn bidentate coordination mode, and two other 4-cba ligands chelate these two Tb(Ⅲ) ions. The title complex molecules are connected through π-π stacking interactions to generate a one-dimensional supramolecular chain, The characteristic infrared spectra, luminescent properties and thermogravimetric analyses have also been discussed.
