10-(6-Hy-droxy-hexa-2,4-diyn-1-yl)-10H-phenothia-zine 5-oxide.


ABSTRACT: The title compound, C(18)H(13)NO(2)S, has two independent mol-ecules (A and B) with similar conformations in the asymmetric unit. Both phenothia-zine moieties have a butterfly structure [dihedral angles between benzene rings = 155.17 (7) and 161.71 (7)°, respectively], and the central six-membered rings have a boat form. In the crystal, the A and B mol-ecules stack alternately along the b axis. The A and B mol-ecules are linked by O-H⋯O=S hydrogen bonds, forming zigzag chains along [10-1].
