4-(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-Butylamino-3-nitrobenzoic acid
The asymmetric unit of the title compound, C(11)H(14)N(2)O(4), comprises four crystallographically independent mol-ecules (A, B, C and D) with similar geometries. In each mol-ecule, the butyl-amino side chain is in an extended conformation, and the carboxyl and butyl-amino groups are almost coplanar with the attached benzene ring; the nitro group is slightly twisted away from the benzene ring. ...
متن کامل4-(3-Methoxyphenoxy)butyric acid
In the title compound, C(11)H(14)O(4), an inter-mediate for the synthesis of a new kind of estrogen receptor modulator, all non-H atoms lie on a common plane (r.m.s. deviation = 0.0472 Å). All C-C bonds in the side chain are in a trans conformation, and the hydroxyl group is also trans to the methyl-ene chain. In the crystal structure, mol-ecules form centrosymmetric dimers showing a head-to-he...
متن کامل4-Ethylamino-3-nitrobenzoic acid
In the title compound, C(9)H(10)N(2)O(4), an intra-molecular N-H⋯O hydrogen-bond inter-action generates an S(6) ring motif. The nitro group is slightly twisted away from its attached benzene ring [dihedral angle = 15.29 (15)°]. In the crystal structure, mol-ecules are stacked down the a axis caused by short O⋯O(-1-x, -y, 2-z) contacts of 2.6481 (16) Å involving the O atoms of the nitro groups. ...
متن کامل3-(4-Pyridyl)benzoic acid
The mol-ecule of the title compound, C(12)H(9)NO(2), is not planar, the benzene and pyridine rings making a dihedral angle of 32.14 (7)°. The carb-oxy group is slightly twisted with respect to the benzene ring by 11.95 (10)°. In the crystal structure, inter-molecular O-H⋯N hydrogen bonds link neighboring mol-ecules into infinite chains along the c axis.
