(E)-5-[(2-Hydroxy-5-methoxybenzylidene)amino]-1,3,4-thiadiazole-2(3H)-thione
In the title thione-Schiff base compound, C(10)H(9)N(3)O(2)S(2), the dihedral angle between the benzene ring and the five-membered ring is 6.69 (8)°. An intra-molecular O-H⋯N hydrogen bond forms an S(2) (2)(6) ring. In the crystal, inversion dimers linked by pairs of N-H⋯S inter-actions occur, generating R(2) (2)(8) ring motifs. The crystal structure features a S⋯S contact [3.3776 (7) Å], which...
متن کامل5-[(E)-(5-Bromo-2-hydroxybenzylidene)amino]-1,3,4-thiadiazole-2(3H)-thione
In the title mol-ecule, C(9)H(6)BrN(3)OS(2), the dihedral angle between the benzene ring and the five-membered ring is 5.5 (3)°. An intra-molecular O-H⋯N hydrogen bond forms an S(6) ring motif. In the crystal, N-H⋯S hydrogen bonds link mol-ecules into centrosymmetric dimers creating R(2) (2)(8) ring motifs. In addition, there are inter-molecular S⋯S [3.430 (2) Å] contacts. The crystal used was ...
متن کامل5-Ethoxy-1,3,4-thiadiazole-2(3H)-thione
In the title compound, C(4)H(6)N(2)OS(2), the dihedral angle between the five-membered heterocyclic ring and the plane of the eth-oxy group is 4.9 (2)°. The 1,3,4-thiadiazole-2-thione unit is planar, with an r.m.s. deviation of 0.011 Å from the corresponding squares plane defined by the seven constituent atoms. In the crystal, pairs of N-H⋯S hydrogen bonds link the mol-ecules into inversion dim...
متن کاملSynthesis, Characterization and Microbial Activity of 5-[1-(1,3-Benzothiazol-2-Ylsulfanyl)Alkyl]-1,3,4-Thiadiazole-2-(3h)-Thione
A number of benzothiazole-2-ylsulfanyl derivatives 2(1,3-Benzothiazol-2-ylsulfanyl)alkanoylhydrazide (IA – IG) and 5-[1-(1,3-Benzothiazol-2-ylsulfanyl)alkyl]-1,3,4-thiadiazole-2(3H) thione (IIA-IIG) have been synthesised from (1,3Benzothiazol-2-ylsulfanyl)acetic acid. These compounds were synthesied and characterized from their F.T.I.R, and H-NMR spectral studies. The compound (IIA to IIG) were...
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 ...
