文摘

The in situ [2+3] cycloaddition reaction of 1,3-dithiole-2-carbonitrile and NaN₃ in the presence of ZnSO₄·7H₂O, water and ethanol affords a novel 3D-diamond-like networks with diamond subunits as connecting nodes, [(CN₄-C₃H₂S₂)₂Zn]_n, (1). X-ray diffraction structural analysis reveals that complex 1 crystallized in tetragonal crystal system and with I-42d space group. The second harmonic generation (SHG) measurement reveals that 1 is nonlinear optical active with SHG efficiency approximately 0.7 times of the standard potassium dihydrogen phosphate (KDP). Moreover, complex 1 exhibits strong blue fluorescent emissions at λ_max = 447 nm in the solid state at room temperature.
