Crystal structure of ethyl 2-(1H-benzimidazol-2-yl)-2-[2-(4-nitrophenyl)hydrazinylidene]acetate
The title compound, C17H15N5O4, was obtained via the condensation of 3-eth-oxy-2-[2-(4-nitro-phen-yl)hydrazono]-3-oxo-propanoic acid with 1,2-di-amino-benzene. In the mol-ecule, the dihedral angles between the acetate group and the two aromatic subunits (benzimidazole and nitro-phenyl-hydrazone) are 7.35 (9) and 18.23 (9)°, respectively. Intra-molecular N-H⋯O and N-H⋯N contacts occur. In the cr...
متن کاملCrystal structure of methyl 2-[5-(2-hydroxyphenyl)-2H-tetrazol-2-yl]acetate
The title compound, C10H10N4O3, was synthesized by the esterification of hy-droxy-phenyl tetra-zole. There is an intra-molecular O-H⋯N hydrogen bond present involving the hy-droxy group and the tetra-zole ring. The tetra-zole ring is inclined to the phenol ring by 2.85 (13)°, while the methyl acetate group is almost normal to the tetra-zole ring, making a dihedral angle of 82.61 (14)°. In the c...
متن کاملCrystal structure of 1H-imidazol-3-ium 2-(1,3-dioxoisoindolin-2-yl)acetate
The title salt, C3H5N2 (+)·C10H6NO4 (-), was obtained during a study of the co-crystallization of N'-[bis-(1H-imidazol-1-yl)methyl-ene]isonicotinohydrazide with (1,3-dioxoisoindolin-2-yl)acetic acid under aqueous conditions. The 1,3-dioxoisoindolinyl ring system of the anion is essentially planar [maximum deviation = 0.023 (2) Å]. In the crystal, cations and anions are linked via classical N-H⋯...
متن کاملCrystal structure of methyl 2-(7-hy-droxy-2-oxo-2H-chromen-4-yl)acetate.
In the title coumarin derivative, C12H10O5, the fused ring system is almost planar (r.m.s deviation = 0.016 Å). The Car-C-C=O torsion angle of the side chain is -8.4 (2)° In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, generating C(8) chains propagating in the [100] direction. The chains are cross-linked by weak C-H⋯O inter-actions, thereby generating undulating (001) sheets.
متن کاملCrystal structure of ethyl 2-[2-(4-methyl-benzo-yl)-5-p-tolyl-1H-imidazol-1-yl]acetate.
In the title compound, C22H22N2O3, the plane of the five-membered ring is oriented at dihedral angles of 45.4 (1) and 52.5 (1)° to the phenyl rings. Furthermore, this ring makes an angle of 85.2 (2)° with the plane of the ethyl acetate substituent. The mol-ecular structure is affected by an intra-molecular C-H⋯O hydrogen bond between an H atom from the p-tolyl group and the carbonyl O atom of t...
