Crystal structure of (E)-2-(2-chloro-6-hydroxybenzylidene)hydrazine-1-carbothioamide, C8H8ClN3O4S

“…Because of the consequence of repulsion between the nitrogen lone pairs and the adjacent N bonds, the C=N-N angle of 115.11(17)°(C2 = N3-N2) is much smaller than the ideal value of 120°expected for sp 2 N atoms. The C1 = S1 bond distance in the molecule is 1.698(2) Å, which is between the typical C=S double-bond (1.56 Å) and the typical C- A database search gave the result that the structure of the parent compound (without the chloro substituent) [3] and another very closely related structure is known [4].…”

“…Thiosemicarbazones are a class of important Schiff-bases and have received considerable attention for many years because of their biological activities and coordination chemistry properties [3][4][5][6][7][8][9][10][11][12][13][14]. In order to search for new thiosemicarbazones, the title compound was synthesized and its crystal structure was determined.…”

“…Schiff-bases and their derivatives have received continuous attention and been investigated for many years due to their bioactivity, pharmacy and applications in coordination chemistry. Especial for the Schiff bases containing halogen atom are particular interest because of their higher biological activities [3][4][5][6][7]. In order to search for new Schiff bases containing halogen substituents, the title compound was synthesized and its crystal structure determined.…”
