The title molecule, C11H15NOS, consists of a seven-membered azepine ri
ng fused to both a five-membered thiophene ring and a six-membered pip
eridine ring so that a methylene bridge links positions 5 and 9, The t
hiophene ring is planar, while the azepine ring adopts a pseudo-chair
conformation with a pseudo-equatorial hydroxy group at C10. The 1,3-fu
sed piperidine ring also possesses a chair conformation.
