(E)-5-[(3-Ethoxy-2-hydroxybenzylidene)amino]-1,3,4-thiadiazole-2(3H)-thione
In the title compound, C(11)H(11)N(3)O(2)S(2), the dihedral angle between the benzene ring and the five-membered ring is 6.85 (9)°. An intra-molecular O-H⋯N hydrogen bond makes an S(6) ring motif. In the crystal, mol-ecules are linked through bifurcated N-H⋯(O,O) hydrogen bonds with R(1) (2)(5) ring motifs, forming chains along the b axis. A short C⋯S contact [3.3189 (19) Å], which is shorter t...

In the title compound, C(10)H(9)N(3)O(2)S(2), the dihedral angle between the benzene ring and the five-membered ring is 1.54 (13)°. An intra-molecular O-H⋯N hydrogen bond makes an S(6) ring. In the crystal, mol-ecules are linked together through bifurcated N-H⋯(O,O) hydrogen bonds having R(1) (2)(5) ring motifs, forming chains along the b axis. The crystal structure also features π-π inter-acti...
متن کامل3-Benzamidomethyl-4-[(E)-2-chlorobenzylideneamino]-1H-1,2,4-triazole-5(4H)-thione
In the title compound, C(17)H(14)ClN(5)OS, the dihedral angles formed by the two benzene rings with the triazole ring are 66.88 (3) and 19.16 (3)°, and the benzene rings are inclined to each other with a dihedral angle of 78.40 (3)°. Inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into layers parallel to the (100) planes, and centrosymmetric π-π stacking inter-actions [centroid-centroi...
متن کامل5 - Amino - 3 - methyl - 1 , 2 , 4 - thiadiazole
An improved procedure for isolation of 5-amino-3-methyl-1,2,4-thiadiazole in pure form on a multi-gram scale without chromatography is reported. Its 1H and 13C-NMR and IR data are presented and previously published erroneous data corrected. The molecular structure is confirmed by X-ray diffraction which shows layers consisting of an elaborate two-dimensional hydrogen bonded network of molecules.
متن کاملSynthesis and Leishmanicidal Activity of 1-[5-(5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl]-4-benzoylepiperazines
A series of (5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl derivatives 6a–6e have been synthesized and screened for in vitro anti-leishmanial activity against the promastigote form of L. major. The structure of Schiff bases were confirmed by 1H NMR, IR. Screening results indicate that all of the designed and synthesized final compounds (6a-6e) significantly reduced the viability of promastigotes ...
