A novel binuclear Ag(I) complex [Ag_2(C_6H_6N_3O)_2(C_6H_7N_3O)_2]·2CH_3CN (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) , β = 127.7150(10)°, V = 3348.6(2) ~3, D_c = 1.675 g/cm~3, M_r = 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 CH_3CN solvate molecule in the asymmetric unit of complex 1.
