摘要
A fluorescent Ni（II） complex 1, [Ni（OH-H2Bdc）（Bibimp）]n·nH2O, constructed with 5-hydroxyisophthalic acid（OH-H2Bdc） and 2,6-bis（2-benzimidazolyl）pyridine）（Bibimp） has been synthesized by hydrothermal methods and structurally characterized by elemental analysis, IR spectroscopy, TG/DTG, fluorescence spectrum and single-crystal X-ray diffraction. The title complex crystallizes in triclinic system, space group P1 with a = 10.187（2）, b = 10.273（2）, c = 13.401（3）A, α = 69.65（3）, β = 69.66（3）, γ = 70.61（3）°, V = 1196.8（4） A3, and Z = 2. The adjacent chains of complex 1 are stacked offset with respect to each other in an ABAB fashion by van der Waals interactions, and only a weak interlayer nonclassical C–H…O hydrogen bond has been observed. Complex 1 displays strong blue fluorescent emissions at 483 nm in the solid state upon photo-excitation at 365 nm at room temperature.
