Abstract:
The title compound, C29H24N2OS, contains a pheno-thia-zine moiety linked to a planar carbazole unit (r.m.s. deviation = 0.029 Å) by a C-C single bond. The pheno-thia-zine moiety possesses a typical non-planar butterfly structure with a fold angle of 27.36 (9)° between the two benzene rings. The dihedral angle between the mean planes of the carbazole and pheno-thia-zine units is 27.28 (5)°. In the crystal, mol-ecules stack in pairs along the c-axis direction, linked by offset π-π inter-actions [inter-centroid distance = 3.797 (1) Å]. There are C-H⋯π inter-actions present linking these dimers to form a three-dimensional structure.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.

Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...
