3-Acetyl-4-hydroxyphenyl acrylate
In the title compound, C(12)H(12)O(4), the hydr-oxy O and the C and O atoms of the acetyl group are almost coplanar [maximum deviation = 0.0356 (1) Å] with the benzene ring. The dihedral angle between the benzene ring and the plane through the non-H atoms of the methacrylo-yloxy group is 86.1 (1)°. In the crystal structure, mol-ecules are linked by two C-H⋯O hydrogen bonds, forming dimers with ...

In the title m-terphenyl derivative, C22H17NO4, the dihedral angles between the aromatic rings of the benzoic acid-acetophenone, acetophenone-benzamide and benzoic acid-benzamide units are 45.39 (8), 48.02 (8) and 42.93 (8)°, respectively. The carbamoyl and carboxyl groups are disordered with a refined occupancy ratio of 0.558 (15):0.442 (15). In the crystal, mol-ecules are linked through O-H⋯O...
متن کامل4-(But-3-enylamino)-3-nitrobenzoic acid
The asymmetric unit of the title compound, C(11)H(12)N(2)O(4), contains 12 crystallographically independent mol-ecules, labelled A to L. The nitro and carboxyl groups are twisted slightly out of the plane of the attached benzene ring in all independent mol-ecules except mol-ecules G and D. The nitro group is coplanar with the benzene ring in mol-ecule G and the carboxyl group is coplanar with t...
متن کامل4-Acetyl-3-[2-(ethoxycarbonyl)phenyl]sydnone
Sydnones, which contain a mesoionic five-membered heterocyclic ring, are more stable if synthesized with an aromatic substutuent at the N3 position. In the title compound {sys-tematic name: 4-acetyl-3-[2-(eth-oxy-carbon-yl)phen-yl]-1,2,3-oxa-diazol-3-ylium-5-olate}, C13H12N2O5, the aromatic substitutent is 2-(eth-oxy-carbon-yl)phenyl. Intra- and inter-molecular hydrogen bonds are observed. The ...

THE ASYMMETRIC UNIT OF THE TITLE COMPOUND [SYSTEMATIC NAME: 4-acetyl-3-(4-meth-oxy-phen-yl)-1,2,3-oxadiazol-3-ium-5-olate], C(11)H(10)N(2)O(4), contains four crystallographically independent mol-ecules. The 1,2,3-oxadiazole rings are almost planar [maximum deviations = 0.006 (3), 0.006 (3), 0.002 (3) and 0.009 (3) Å] and form dihedral angles of 55.03 (14), 61.02 (13), 58.36 (14) and 53.79 (15)°...
