Novel acetylpyrazine thiocarbohydrazone （ 1 ）, 1-acetylpyrazine-5-[ 5-bromosalicylaldehyde ]-dithiocarbohydrazone （ 2a ）, 1-acetylpyrazine-5-[ 5-chlorosalicylaldehyde ]-dithiocarbohydrazone （ 2b ）, and 1-acetylpyrazine-5- [ 5-nitrosalicylaldehyde ]- dithiocarbohydrazone （2c） have been synthesized and characterized by IR,1^H NMR, MS spectra and element analysis. The crystal structure of compound 1 was determined by X-ray single crystal diffraction analysis. Crystal structure of compound 1 belongs to monoclinic system with space C2/c. The unit cell parameters are α=2.3057（14）nm, b=0.7297（4）nm, c = 1.1940（7）nm, V= 1.909（2）nm^3, Z=8, Dr = 1.463g/cm^3, μ = 0.309mm^-1 , F（000） = 880, R1 = 0.0866, wR2 = 0.2072.
