1-Benzyl-3,5-bis­[(E)-3-thienyl­methyl­idene]piperidin-4-one

In the title mol­ecule, C(22)H(19)NOS(2), the piperidine ring adopts an envelope conformation with the benzyl substituent in an equatorial position. Each of the olefinic double bonds has an E configuration. The dihedral angle between the two thio­phene rings is 1.55 (18)°. The thio­phene rings form...

description In the title mol­ecule, C(22)H(19)NOS(2), the piperidine ring adopts an envelope conformation with the benzyl substituent in an equatorial position. Each of the olefinic double bonds has an E configuration. The dihedral angle between the two thio­phene rings is 1.55 (18)°. The thio­phene rings form angles of 72.21 (14) and 73.43 (14)° with the phenyl ring. Both thio­phene rings are disordered over two orientations [occupancy ratios of 0.799 (1):0.201 (1)] at 180° from one another. In the crystal, weak inter­molecular C—H⋯O hydrogen bonds and C—H⋯π inter­actions help to stabilize the packing.
