Crystal structure of (Z)-2-benzyl-idene-4-methyl-2H-benzo[b][1,4]thia-zin-3(4H)-one.

ABSTRACT: In the title compound, C16H13NOS, the 1,4-thia-zine 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 mol-ecule. In the crystal, mol-ecules are linked by pairs of C-H?O hydrogen bonds, forming inversion dimers.

In the title compound, C16H13NOS, the 1,4-thia-zine 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 mol-ecule. In the crystal, mol-ecules are linked by pairs of C-H⋯O hydrogen bonds, forming inversion dimers. ...[more]
