The structure was confirmed via elemental analysis, MS, ^1H NMR, IR, and X-ray diffraction. It crystallized in a monoclinic system with space group P2 （ 1 ）, α = 0.4905（1） nm, b =0. 8160（2） nm, c = 1.4105（3） nm, β =93. 33（3）°, Z=2, V=0.5636（2） nm^3, Do =1.457 Mg/m^3,μ =0. 112 mm^-1 , F（000） =256, and final R1 =0. 0685. Several intermolecular hydrogen-bond interactions existed in the crystal structure, facilitating the stabilization of the compound.展开更多

The acetohyrazide derivatives 3 and 5 were utilized as a key intermediate for the synthesis of a novel heterocyclic compounds. The synthesis of a novel series of condensation and substituted derivatives of 2-(benzo[d]thiazol-2’-ylthio) acetohydrazide in good yield has been reported. The newly synthesized compounds were characterized by elemental analysis 1H-NMR, <sup>13</sup>C-NMR spectra and X-ray crystallographic investigations. The reported crystal structures of these novel 2-(benzo[d] thiazol-2’-ylthio)acetohydrazide derivatives are expected to be a remarkable contribution to the crystallographic database of heterocyclic compounds.展开更多
