Crystal structure of (Z)-2-benzylidene-4-methyl-2H-benzo[b][1,4]thiazin-3(4H)-one

Crystal structure of (Z)-2-benzylidene-4-methyl-2H-benzo[b][1,4]thiazin-3(4H)-one

In the title compound, C16H13NOS, the 1,4-thiazine ring displays a screw-boat conformation. The conformation about the ethene bond [1.344 (2) Å] is Z. The plane of the fused benzene ring makes a dihedral angle of 58.95 (9)° with the pendent phenyl ring, indicating a twisted conformation in the molec...

Description
Summary:In the title compound, C16H13NOS, the 1,4-thiazine ring displays a screw-boat conformation. The conformation about the ethene bond [1.344 (2) Å] is Z. The plane of the fused benzene ring makes a dihedral angle of 58.95 (9)° with the pendent phenyl ring, indicating a twisted conformation in the molecule. In the crystal, molecules are linked by pairs of C—H...O hydrogen bonds, forming inversion dimers.
