摘要：

The title compound l-benzyl-5-(（4-methoxyphenyl）ethynyl)-4-phenyl-1H-1,2,3-triazole(C;H;N;O) was designed and synthesized using one-pot strategy and structural characterization was done by single-crystal X-ray diffraction,NMR,IR and MS.This compound was crystallized out from an ethanolic solution in triclinic system,space group P1 with a =9.9038（9）,b = 10.2928（9）,c = 18.8715（19） ?,α = 103.541（6）,β = 90.507（7）,γ = 97.157（7）°,V =1854.2（3） ?;,Z = 4,crystal size（mm） = 0.25 × 0.1 × 0.1 and R;= 0.068.Its asymmetric unit contains two independent molecules.The crystal structure of the title compound is stabilized by intramolecular interactions of types C-H…N and C-H…O.Additionally,X-ray analysis reveals obvious C-H…π,π-π stacking interactions between two adjacent aromatic ring planes.
