摘　　要：A novel binuclear Ag（I） complex [Ag2（C6H6NaO）2（C6H7N3O）2]·2CH3CN （1） was synthesized by the evaporation reaction of silver nitrate and （E）-1-（pyrazin-2-yl）ethanone oxime （HL）. The complex was characterized by elemental analysis, IR spectrum and X-ray single-crystal diffraction analysis. It crystallizes in the monoclinic space group C2/c with a = 22.7089（3）, b = 11.5443（7）, c = 16.1468（4）/A, β = 127.7150（10）°, V= 3348.6（2） A^3, Dc = 1.675 g/cm^3, Mr = 844.42, Z = 4, F（000） = 1696.0,μ = 1.226 mm^-1, the final R =0.0250 and wR = 0.070. The coordination around the silver（I） atom is a distorted trigonal-bipyramidal geometry involving one protonated pyrazinyl oxime ligand （HL）, one deprotonated oxime ligand （L^-） and one CH3CN solvate molecule in the asymmetric unit of complex 1.A novel binuclear Ag（I） complex [Ag2（C6H6NaO）2（C6H7N3O）2]·2CH3CN （1） was synthesized by the evaporation reaction of silver nitrate and （E）-1-（pyrazin-2-yl）ethanone oxime （HL）.
