(Z)-3-(3,4-Dimeth-oxy-benzyl-idene)-2,3-dihydro-1,5-benzothia-zepin-4(5H)-one.

Project description:In the title compound, C18H17NO3S, the seven-membered thia-zepine ring adopts a slightly distorted sofa conformation. The dihedral angle between the mean plane of the benzothia-zepine ring system and the benzene ring is 5.9?(1)°. The mol-ecular conformation is stabilized by an intra-molecular C-H?S hydrogen bond, which generates an S(7) ring motif. In the crystal, N-H?O and C-H?O hydrogen bonds link inversion-related mol-ecules into dimers, incorporating R 1 (2)(6) and R 2 (2)(8) ring motifs; the acceptor O atom is bifurcated. These dimers are further linked by C-H?O hydrogen bonds, forming supra-molecular tapes running along the a axis. These are connected into the three-dimensional architecture by C-H?? inter-actions.

Project description:In the title compound, C(10)H(10)N(2)O(2)S, the thia-zine ring approximates to an envelope form with the S atom in the flap position.

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

Project description:In the title compound, C(15)H(11)NO(2)S, the dihedral angle between the aromatic rings is 80.35?(7)°.
