4-(2-Benzoylethyl)benzoic acid
The title compound, C(16)H(14)O(3), adopts a conformation in which each functional group is almost coplanar with its adjacent ring, while the two aromatic rings are twisted with respect to one another with a dihedral angle of 78.51 (3)°. The compound dimerizes by standard centrosymmetric hydrogen-bonded carboxyl pairing [O⋯O = 2.6218 (11) Å and O-H⋯O = 176 (2)°]. The packing includes two inter-...

In the title compound, C(15)H(14)N(2)O(5)S, two similar mol-ecules comprise the asymmetric unit, which are linked by strong inter-molecular C-H⋯π inter-actions. Both mol-ecules are bent, with dihedral angles of 71.94 (16) and 74.62 (15)° between the benzene rings. An intra-molecular N-H⋯O hydrogen bond occurs in each mol-ecule. In the crystal, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds link...

In the title compound, C(13)H(10)BrNO(4)S, the dihedral angle between the benzene rings is 82.75 (15)°. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal structure, two mol-ecules form an R(2) (2)(8) centrosymmetric dimer through a pair of O-H⋯O hydrogen bonds. Intra- and inter-molecular C-H⋯O hydrogen bonds are also observed.

In the title mol-ecule, C(12)H(9)NO(2)S, the dihedral angle between benzene and thio-phene rings is 41.91 (8)°. The crystal packing exhibits short inter-molecular O-H⋯O and C-H⋯O hydrogen-bonding contacts.
متن کامل2-Methyl-4-(2-methylbenzamido)benzoic acid
In the crystal structure of the title compound, C(16)H(15)NO(3), inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains parallel to the b axis and pairs of inter-molecular O-H⋯O hydrogen bonds between inversion-related carb-oxy-lic acid groups link the mol-ecules into dimers. The dihedral angle between the two benzene rings is 82.4 (2)°.
