Abstract:The title compound(C14H10N4S2) has been synthesized by ring-closing reaction of dithizone and carbon bisulfide. Its structure was determined by single-crystal X-ray diffraction. The crystal belongs to the monoclinic system, space group C2/c with a = 25.169(5), b = 3.9690(8), c = 30.130(6) ?,β= 113.79(3)°, Z = 8, V=2754.0(1)?3 , Mr=298.38, Dc=1.439g/cm3, Z=8, μ(MoKα)=3.80cm-1, F(000)=1232. The structure was solved by direct methods, and refined by full-matrix least-square method to a final R=0.0335 and wR = 0.0861. The atoms of N(1), N(2), C(13) ,C(14) and S(1) are coplanar, with the maximum deviation of 0.010(1)
Keywords:ring-closing reaction  synthesis  crystal structure
