چکیده
In the title molecule, C(21)H(14)N(2)O(2), the anthracenyl system is approximately planar [maximum deviation = 0.056 (4) Å] and is oriented at a dihedral angle of 73.6 (1)° with respect to the benzene ring. An intra-molecular C-H⋯N hydrogen bond generates an S(6) ring motif. The crystal packing is stabilized by C-H⋯π and π-π inter-actions [centroid-centroid distances of 3.688 (2), 3.656 (1) and 3.716 (2) Å].

In the title compound, C(24)H(18)ClN(3)O(2)S, the dihedral angle between the benzene ring and the anthracene ring system is 41.10 (8)°. The thia-zine ring has a half-chair conformation and the Cl atom is in an axial orientation. In the crystal, mol-ecules are linked by C-H⋯O inter-actions, generating C(8) chains along [100]. A C-H⋯N short contact occurs in the mol-ecule, generating an S(6) ring.
