摘　　要：A binuclear cuprous complex [Cu（μ-I）（NPPh）]2（1,NPPh = 1-（2-（diphenylphosphanyl）phenyl）-3-phenyl-4,5-dihydro-1 H-pyrazole） was synthesized and characterized by elemental analysis,NMR and X-ray single-crystal structure analysis.It crystallizes in triclinic space group P2_1/n with a = 10.7520（3）,b = 18.1860（5）,c = 11.8487（3） ？,β = 91.864（2）,V = 2315.61（11） ？~3,Z = 4,Mr = 594.87,Dc = 1.706 g/cm^3,F（000） = 1176.0,μ = 12.582 mm（-1）,GOOF = 1.048,the final R = 0.0289 and wR = 0.0670 for 3787 observed reflections with I 〉 2σ（I）.The Cu atoms in the complex are four-coordinated and adopt distorted tetrahedral coordination geometry.In the solid state,the complex exhibits greenish yellow photoluminescence with a peak maximum of 533 nm,a decay time of 34 μs,and a photoluminescence quantum yield of 63.6% at room temperature,respectively.
