3-Acetoxy-2-naphthoic acid
In the title compound, C(13)H(10)O(4), an analog of acetyl-salicylic acid, the naphthalene unit is twisted slightly due to ortho disubstitution [dihedral angle between conjugated rings system in the naphthalene unit = 2.0 (2)°]. The mean planes of the carb-oxy-lic and ester groups are almost coplanar and perpendicular, respectively, to the mean plane of the conjugated aromatic system, making di...
متن کاملIsonicotinamide–2-naphthoic acid (1/1)
In the title 1:1 adduct, C(6)H(6)N(2)O·C(11)H(8)O(2), the amide group is slightly twisted out of the plane of the aromatic ring, with a C-C-C-N torsion angle of 25.11 (19)°, whereas the carb-oxy-lic acid group is approximately coplanar with the bicylic ring system, with a C-C-C-O torsion angle of 10.9 (2)°. The amide groups from two isonicotinamide mol-ecules form a dimer via N-H⋯O hydrogen bon...

The asymmetric unit of the title compound, C(21)H(18)O(3), contains two crystallographically independent mol-ecules. The two mol-ecules are linked into cyclic centrosymmetric dimers R(2) (2)(8) by O-H⋯O hydrogen bonds. The dihedral angles between the naphthalene ring system and the benzene ring are 87.0 (8) and 84.4 (2)° in the two mol-ecules. The crystal packing is stabilized by O-H⋯O, C-H⋯π a...
متن کامل6-Nicotinamido-2-naphthoic acid
In the title mol-ecule, C(17)H(12)N(2)O(3), the naphthalene ring system and the pyridin-3-yl rings are nearly coplanar with a dihedral angle between them of 2.28 (8)°. In the crystal, the hy-droxy and amide N atoms participate in hydrogen bonds, which connect the mol-ecules into a two-dimensional network parallel to (101).
متن کامل4-Amino-3-bromobenzoic acid
The asymmetric unit of the title compound, C(7)H(6)BrNO(2), consists of two mol-ecules having a small variation of bond lengths and angles. The title compound forms dimers through pairs of O-H⋯O hydrogen bonds involving the carboxyl-ate groups. The dimers are linked into polymeric forms through inter-molecular hydrogen bonds, forming R(2) (1)(6), R(3) (2)(8) and R(3) (3)(15) ring motifs.
