2-Benzoyl-2H-1,4-benzothia-zin-3(4H)-one.

ABSTRACT: In the title compound, C(15)H(11)NO(2)S, the dihedral angle between the aromatic rings is 80.35?(7)°. The heterocyclic six-membered ring is not planar: the puckering parameters of this ring are Q = 0.5308?(15)?Å, ? = 63.11?(18) and ? = 23.5?(2)°. The mol-ecules are linked into inversion dimers with R(2) (2)(8) ring motifs by pairs of N-H?O hydrogen bonds. The dimers are inter-linked into polymeric sheets extending parallel to the bc plane by C-H?O hydrogen bonds, generating R(2) (1)(7) ring motifs. ?-? inter-actions occur between the benzoyl phenyl rings with centroid-centroid separations of 3.9187?(15)?Å.

In the title compound, C(15)H(11)NO(2)S, the dihedral angle between the aromatic rings is 80.35 (7)°. The heterocyclic six-membered ring is not planar: the puckering parameters of this ring are Q = 0.5308 (15) Å, θ = 63.11 (18) and ϕ = 23.5 (2)°. The mol-ecules are linked into inversion dimers with R(2) (2)(8) ring motifs by pairs of N-H⋯O hydrogen bonds. The dimers are inter-linked into polymeric sheets extending parallel to the bc plane by C-H⋯O hydrogen bonds, generating R(2) (1)(7) ring moti  ...[more]
