(2Z)-2-Benzylidene-4-n-butyl-3,4-dihydro-2H-1,4-benzothiazin-3-one
In the title compound, C19H19NOS, the six-membered hetero-cyclic ring of the benzo-thia-zine fragment exhibits a screw boat conformation. The plane of the fused benzene ring makes a dihedral angle of 72.38 (12)° with that of the terminal phenyl ring, and is nearly perpendicular to the mean plane formed by the atoms through the n-butyl chain, as indicated by the dihedral angle of 88.1 (2)°. In t...

The azomethine double-bond in the title Schiff base, C(20)H(22)N(4)O, has an E-configuration. The aromatic ring of the benzyl-idene portion (r.m.s. deviation 0.011 Å) and the five-membered pyrazolyl ring (r.m.s. deviation 0.033 Å) form a dihedral angle of 19.0 (1)°. The phenyl substituent is twisted by 55.0 (1)° with respect to the five-membered ring.

In the crystal structure of the title compound, C(22)H(19)N(3)O(3), inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into a zigzag chain parallel to the face diagonal of the ac plane. The meth-oxy phenyl rings make a dihdral angle of 32.38 (7)° and form dihedral angles of 0.66 (8) and 24.17 (7)° with the fused benzooxazine ring system.
متن کامل(2Z)-2-Benzylidene-4-(prop-2-yn-1-yl)-2H-1,4-benzothiazin-3(4H)-one
The mol-ecule of the title compound, C18H13NOS, is build up from two fused six-membered rings, with the heterocyclic component linked to a benzyl-idene group and to a prop-2-yn-1-yl chain. The six-membered heterocycle adopts a distorted screw-boat conformation. The prop-2-yn-1-yl chain is almost perpendicular to the mean plane through benzo-thia-zine as indicated by the C-N-C-C torsion angle of...
