Crystal structure of 4-amino-1-benzyl-1,2,4-triazolin-5-one
The title compound, C9H10N4O, was obtained unintentionally by hydrolysis of 4-amino-1-benzyl-5-methyl-sulfanyl-1,2,4-triazolium tetra-fluoro-borate in the presence of sodium azide. In the crystal, alternating layers of polar amino-triazolinone and apolar benzene moieties are observed. N-H⋯O hydrogen bonds between the amino and carbonyl groups form infinite chains along [010]. These infinite cha...
متن کاملCrystal structure of 3-benzyl-1-[(cyclohexylidene)amino]thiourea
The conformation of the title compound, C14H19N3S, is partially determined by an intra-molecular N-H⋯N hydro-gen-bond inter-action, although the N-H⋯N angle of 108° is quite small. The cyclo-hexyl-idene ring has a chair conformation and its mean plane is inclined to the benzene ring by 46.30 (8)°. In the crystal, mol-ecules are linked by pairs of N-H⋯S hydrogen bonds, forming inversion dimers, ...
متن کاملCrystal structure of (E)-1-[4-({4-[(4-methoxybenzylidene)amino]phenyl}sulfanyl)phenyl]ethan-1-one
The title Schiff base compound, C22H19NO2S, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. Both mol-ecules have an E conformation about the C=N bond. The two mol-ecules differ in the orientation of the aromatic rings with respect to each other. The outer 4-meth-oxy-benzene ring is inclined to the central benzene ring and the outer 4-acetyl-benzene ring by 1.80 (1...
متن کاملSYNTHESIS OF 4-(1-BENZYL-5-IMIDAZOLYL)-1,4-DIHYDROPYRIDINES
The o-nitrophenyl group at position 4 of dihydropyridine of nifedipine analogues was replaced with 2-alkylthio-1-benzyl-5-imidazolyl substituent. Starting from dihydroxyacetone 2-alkythio-1-benzyl- 5-formyl imidazole (3) was first synthesized which was subsequently used in synthesizing symmetrical (5a-f) and asymmetrical (6a,b) dihydropyridines. Primarily pharmacological studies of the title co...
متن کاملCrystal structure of (2E,4E)-5-[bis(2-hydroxyethyl)amino]-1-(4-chlorophenyl)-5-phenylpenta-2,4-dien-1-one
In the title compound, C21H22ClNO3, the penta-diene unit is nearly planar [maximum deviation = 0.023 (1) Å], but the carbonyl O atom deviates significantly [by 0.304 (1) Å] from its mean plane, which is twisted with respect to the phenyl and chloro-benzene rings by 71.34 (13) and 46.40 (13)°, respectively. In the crystal, inversion-related molecules are linked by two pairs of O-H⋯O hydrogen bon...
