摘　　要：The title compound 2-（5-（4-chlorophenyl）-1-phenyl-4,5-dihydro-1H-pyrazol-3-yl）- pyridine（C20H16ClN3, Mr = 333.81） has been synthesized and its crystal structure was determined by single-crystal X-ray diffraction. The crystal belongs to monoclinic, space group P21/n with a = 10.9925（12）, b = 11.0378（12）, c = 14.2751（18） , β = 98.074（11）°, V = 1714.9（3）3, Z = 4, Dc = 1.293 g/cm3, μ（MoKα） = 0.228 mm-1, F（000） = 696, the final R = 0.0521 and wR = 0.1349 for 3495 observed reflections with I 〉 2σ（I）. Intermolecular C–H...π interactions and π-π stacking interactions stabilize the crystal structure. The binding study by fluorescence spectroscope titration showed that the title compound can selectively recognize Fe3＋ in THF solution with fluorescence quenching.The title compound 2-（5-（4-chlorophenyl）-1-phenyl-4,5-dihydro-1H-pyrazol-3-yl）- pyridine（C20H16ClN3, Mr = 333.81） has been synthesized and its crystal structure was determined by single-crystal X-ray diffraction.
