2-[(2-Hy­droxy­naphthalen-1-yl)methyl­idene­amino]-5,6,7,8-tetra­hydro-4H-cyclo­hepta­[b]thio­phene-3-carbonitrile

Two independent mol­ecules, A and B, comprise the asymmetric unit of the title compound, C(21)H(18)N(2)OS, with the difference in the angle of orientation between the naphthalene ring system and the mean plane of the cyclo­heptyl ring [16.13 (1) in A and 11.48 (5)° in B], being evident. The cyclo­he...

Sumario:Two independent mol­ecules, A and B, comprise the asymmetric unit of the title compound, C(21)H(18)N(2)OS, with the difference in the angle of orientation between the naphthalene ring system and the mean plane of the cyclo­heptyl ring [16.13 (1) in A and 11.48 (5)° in B], being evident. The cyclo­heptyl ring adopts a distorted chair conformation in each mol­ecule with r.m.s. deviations of 0.2345 (4) (A) and 0.2302 (4) Å (B). Intra­molecular O—H⋯N hydrogen bonding generates planar six-membered S(6) loops with r.m.s. deviations of 0.0099 (1) (A) and 0.0286 (1) Å (B).
