Crystal structure of meso-3,3′-(1,4-phenyl­ene)bis­(2-phenyl-2,3,5,6-tetra­hydro-4H-1,3-thia­zin-4-one)

The crystal structure of the title compound – meso-C(26)H(24)N(2)O(2)S(2) with two stereocenters – has half the mol­ecule in the asymmetric unit with the other half generated by a crystallographic center of inversion. The thia­zine ring is in a conformation that is between half-chair and envelope [θ = 52.51 (17)°]. The phenyl ring on the 2-carbon atom of the thia­zine ring is pseudo-axial. The central phenyl ring of the mol­ecule is close to orthogonal to the phenyl rings on either side with an angle of 76.85 (11)° between those planes. In the crystal, pairwise, weak C—H⋯O hydrogen bonds between the central phenyl ring and the oxygen atoms of neighboring mol­ecules result in continuous strips propagating along the a-axis direction. Hydro­phobic inter­actions of the C—H⋯π type are also observed.
