(Z)-2-Thiophen-3-ylmethylene-1-aza-bicyclo[2.2.2]octan-3-one

Abstract

The crystal structure of C12H13NOS, which was obtained in a base-catalysed condensation reaction of thio­phene-3-carbox­aldehyde with 1-aza-bi­cyclo­[2.2.2]­octan-3-one, is presented. The title compound, which contains a double bond connecting an aza­bicyclic ring system to a thio­phen-3-yl­methyl­ene moiety, crystallizes from solution in methanol and has a thienyl ring-flip disorder.
