摘　　要：The title compound bis[-chloro-(o-chloro-benzylidene) hydrazine] (C14H8Cl4N2, Mr = 346.02) has been prepared, and its crystal structure was determined by single-crystal X-ray diffraction. The crystal is of monoclinic, space group P21/n with a = 10.777(2), b = 6.456(2), c = 10.988(3) , b = 90.48(2), V = 764.5(3) 3, Z = 2, Dc = 1.503 g/cm3, F(000) = 348 and ?MoK? = 0.763 mm-1 (l = 0.71073 ?. The structure was refined to R = 0.0793 and wR = 0.2398 for 1694 observed reflections with I > 2s(I). The results of crystal structure determination show that both C(7) and C(7)a are of sp2 hybridization and there exists electronic conjugation in the aza-diene of -C=NN=C.The title compound bis[-chloro-(o-chloro-benzylidene) hydrazine] (C14H8Cl4N2, Mr = 346.02) has been prepared, and its crystal structure was determined by single-crystal X-ray diffraction.
