Isonicotinamide–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...
متن کامل3-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 کامل3-(2,4,6-Trimethylbenzoyl)-2-naphthoic acid
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 کاملCrystal structures of 2-acetyl-4-ethynylphenol and 2-acetyl-4-(3-hydroxy-3-methylbut-1-yn-1-yl)phenol
In the title compounds, C10H8O2, (I), and C13H14O3, (II), the 2-acetyl-4-ethynylphenol unit displays a planar geometry, which is stabilized by an intra-molecular O-H⋯O hydrogen bond. The crystal structure of (I) is constructed of infinite strands, along [101], of C-H⋯O=C hydrogen-bonded mol-ecules, which in turn are linked by C-H⋯π inter-actions. In the crystal of (II), which crystallized with ...
