4-Aminopyridinium 4-nitrobenzoate 4-nitrobenzoic acid
The asymmetric unit of the title compound, C(5)H(7)N(2) (+)·C(7)H(4)NO(4) (-)·C(7)H(5)NO(4), consists of an amino-pyridinium cation, a 4-nitro-benzoate anion and a neutral 4-nitro-benzoic acid mol-ecule. The pyridine ring forms dihedral angles of 64.70 (5)° and 70.37 (5)°, respectively, with the benzene rings of 4-nitro-benzoic acid and 4-nitro-benzoate. In the crystal structure, the cations, a...
متن کامل4-(4-Methoxybenzenesulfonamido)benzoic acid
The asymmetric unit of the title compound, C(14)H(13)NO(5)S, contains two independent mol-ecules in which the dihedral angles between the aromatic rings are 83.45 (11) and 86.65 (9)°. In the crystal, the independent mol-ecules are connected by N-H⋯O and O-H⋯O hydrogen bonds, forming a double-chain structure along [401]. A weak π-π stacking inter-action with a centroid-centroid distance of 3.750...
متن کامل4-(4-Propoxybenzoyloxy)benzoic acid
The title compound, C(17)H(16)O(5), is an important inter-mediate for the synthesis of side-chain ligands for polymeric liquid crystals. The prop-oxy and benzoic acid groups subtend dihedral angles of 4.36 (6) and 55.35 (6)°, respectively, with the central benzo-yloxy unit. The crystal structure is stabilized by an inter-molecular O-H⋯O hydrogen bond.
متن کامل4-(4-Fluorophenoxy)benzoic acid
In the title compound, C(13)H(9)FO(3), the dihedral angle between the two benzene rings is 70.99 (5)°. In the crystal structure, mol-ecules are linked into dimers by centrosymmetric O-H⋯O inter-actions, generating R(2) (2)(8) ring motifs. These dimers are linked into a two-dimensional array, parallel to the ab plane, by two different C-H⋯O inter-actions. A weak C-H⋯π inter-actions is also present.
متن کامل4-(4-Octyloxybenzoyloxy)benzoic acid
The title compound, C(22)H(26)O(5), is an important inter-mediate for the synthesis of side-chain ligands for polymeric liquid crystals. The octyl group is coplanar with the central C(6)O moiety, where the maximum deviation of a C atom in the octyl group from the C(6)O plane is 0.161 (5) Å. The crystal structure is stabilized by inter-molecular O-H⋯O hydrogen bonds.
