A Cu? complex with mix ligands [Cu(HIm)2(PPh3)2](BF4) was synthesized and characterized by elemental analysis, IR spectroscopy and X ray diffraction crystallography. The crystal belongs to monoclinic system and P21/c space group, with cell parameters, a=1.2836(3)nm, b=1.5089(3)nm, c=2.0661(4)nm, α=90°, β=101.464(4)°,γ=90°, V=3.9219(13)nm3, Z=4 and Dc=1.374mg·m-3. The Cu? is coordinated by two P atoms from triphenylphosphine and two N atoms from imidazole to form the distorted tetrahedral geometry.
