organic compounds
The title compound, C7H4Br2O, has mirror symmetry perpendicular to the tropone ring, and forms a head-to-head association of two nearly parallel molecules. Intermolecular π–π, halogen–halogen and C—HO interactions are observed in the crystal structure.
organic compounds
The title compound, also known as 2-amino-5-[4-(octylamino)phenyl]tropone, C21H28N2O, contains two crystallographically independent molecules in the asymmetric unit. The NH2 group of the 2-aminotropone unit and the NH group of the aminobenzene unit participate in intermolecular hydrogen bonding with the O atoms of neighbouring molecules. An intermolecular π–π interaction is observed in the crystal structure.
organic compounds
In the title compound, C15H20N2O2, the N atom of the diethylamine group has a planar environment, whereas the N atom of the dimethylamine group is pyramidal. Intermolecular C—Hπ and C—HO interactions are observed in the crystal structure.
organic compounds
The title compound, C36H58N2O3, also known as a liquid crystalline material, has a phase sequence of crystal–smectic C–isotropic liquid. The two benzene rings are nearly coplanar with the central NNO group, and each paraffin chain has an all-trans conformation. The molecules form a tilted layer structure via intermolecular π–π, C—HO and C—Hπ interactions.
