Abstract

C8H9N3OS, monoclinic, C2/c, a = 14.206 (3), b = 14.244 (4), c = 10.457 (4) A, beta = 116.18(2) degrees, V = 1898.9 (8) A3, Z = 8, Dm = 1.387, D chi = 1.366 g cm-3, lambda(Mo K alpha) = 0.71069 A, mu = 2.90 cm-1, F(000) = 816.0, T = 298 K, final R = 0.0429 for 1322 observed reflections. The S and hydrazinic N atoms lie trans. The lowering of antibacterial activity compared to that of 4-phenylthiosemicarbazide may be correlated with the decrease in negative charge on the hydrazinic N atom. The crystal structure is stabilized by hydrogen bonding, stacking interactions and van der Waals forces.

摘要

C8H9N3OS,单斜晶系,C2/c空间群,a = 14.206 (3),b = 14.244 (4),c = 10.457 (4) Å,β = 116.18(2)°,V = 1898.9 (8) ų,Z = 8,Dm = 1.387,Dc = 1.366 g cm⁻³,λ(Mo Kα) = 0.71069 Å,μ = 2.90 cm⁻¹,F(000) = 816.0,T = 298 K,对1322个观测反射的最终R值为0.0429。硫原子和肼基氮原子呈反式排列。与4-苯基硫代氨基脲相比,抗菌活性的降低可能与肼基氮原子上负电荷的减少有关。晶体结构通过氢键、堆积相互作用和范德华力得以稳定。
