✦ Synopsis

Crystals of the title compound, C 16 H 15 NOS, were obtained from a condensation reaction of benzo[b]thiophene-3-carboxaldehyde with 1-azabicyclo[2.2.2]octan-3-one and subsequent crystallization of the product from methanol. The title compound, containing a double bond that connects an azabicyclic ring system to a benzo[b]thiophen-3-ylmethylene group, was obtained as the Z geometric isomer, crystallizing in the triclinic space group P1.
