3-Chloro-1-methyl-4-[2-(3-phenyl-allyl-idene)hydrazinyl-idene]-3,4-dihydro-1H-2?(6),1-benzothia-zine-2,2-dione.

ABSTRACT: In the title compound, C(18)H(16)ClN(3)O(2)S, the dihedral angle between the aromatic rings is 4.81?(2)° and the alkyl chain takes on an extended conformation [N-C-C-C = 179.2?(4)°]. The conformation of the thia-zine ring is an envelope, with the S atom displaced by -0.805?(3)?Å from the mean plane of the other five atoms (r.m.s. deviation = 0.046?Å). The Cl atom is an axial conformation and is displaced by 1.761?(4)?Å from the thia-zine ring plane. In the crystal, inversion dimers linked by pairs of C-H?O inter-actions generate R(2) (2)(20) loops and further C-H?O hydrogen bonds link the dimers into (001) sheets. Weak aromatic ?-? stacking inter-actions [centroid-centroid separations = 3.870?(3) and 3.883?(3)?Å] are also observed.
