(10-Ethyl-10H-phenothiazine-3,7-diyl)bis(p-tolylmethanone)
Keyword(s):
The title compound, C30H25NO2S, crystallizes with two independent molecules (AandB) having similar conformations in the asymmetric unit. Both phenothiazine units have a butterfly structure; the dihedral angles between the planes of the benzene rings are 17.95 (13) and 12.65 (14)° for moleculesAandB, respectively. In the crystal, theBmolecules are linked by pairs of C—H...O hydrogen bonds, forming inversion dimers with anR22(10) ring motif. TheAmolecules are linked by C—H...π interactions. Layers ofAmolecules and layers ofBmolecules are linked by a second C—H...π interaction, formingA–B–B–Aslabs, which stack back-to-back and lie parallel to thebcplane.
