RESUMO
The seven-membered ring of the title compound, C(12)H(12)N(2)O(3), which is fused with the phenyl-ene ring, adopts a boat-shaped conformation (with the methine C atom as the prow and the phenyl-ene C atoms as the stern); the H atom on the methine linkage exists in an axial position. The five-membered ring that is fused with the seven-membered ring adopts an envelope conformation (with the C atom bearing the hy-droxy substituent representing the flap) [the deviation from the plane defined by the other four atoms is 0.200â (7)â Å in one mol-ecule and 0.627â (5)â Å in the other]. The two independent mol-ecules are disposed about a pseudo center of inversion and are connected by a pair of N-Hâ¯O hydrogen bonds. Adjacent dimers are linked by a pair of O-Hâ¯O hydrogen bonds, generating a chain running along the b axis.
RESUMO
The seven-membered fused-ring in the title compound, C(12)H(12)N(2)S(2), adopts a boat conformation (with the two phenyl-ene C atoms representing the stern and the methine C atom the prow). This methine C atom and the tertiary N atom also belong to a five-membered ring, which has an envelope conformation. In the crystal structure, mol-ecules are linked about a center of inversion by pairs of N-Hâ¯S hydrogen bonds.
