In the title compound, C28H18N2O5, the dihedral angle between the terminal benzoate rings is 20.67 (12)°. The central oxadiazole ring is almost coplanar with its two benzene ring substituents, making dihedral angles of 4.80 (16) and 5.82 (16)°. In the crystal, pairs of C-H⋯O hydrogen bonds form inversion dimers with R 2 (2)(40) ring motifs. The structure… (More)
In the title compound, C(18)H(17)N(3)O·0.5C(2)H(5)OH, the dihedral angles between the central imidazole rings and the pendant benzene rings are 42.06 (15) and 2.01 (16)° in one asymmetric mol-ecule and 47.91 (15) and 7.31 (14)° in the other. An intra-molecular N-H⋯O hydrogen bond occurs in each imidazole mol-ecule. In the crystal, the components are… (More)
In the title compound, C21H23NO6S, the dihedral angle between the thio-pene and benzene rings is 88.66 (6)°. In the crystal, mol-ecules are connected by C-H⋯N and C-H⋯O hydrogen bonds, forming a tape along [10-1]. In addition, C-H⋯π and π-π stacking [centroid-centroid distance = 3.879 (2) Å between the thio-phene rings] inter-actions are observed.
