1-Methyl-3,5-bis-[(E)-(3-methyl-2-thienyl)methyl-ene]piperidin-4-one monohydrate

In the title mol-ecule, C(18)H(19)NOS(2)·H(2)O, the piperidine ring adopts an envelope conformation with the methyl substituent in an equatorial position. Each of the olefinic double bonds has an E configuration. The dihedral angle between the two thio-phene rings is 6.04 (14)°. The water mol-ecule forms two donor inter-actions, one with the carbonyl O atom and the other to the hetero N atom. The centrosymmetric {C(18)H(19)NOS(2)·H(2)O}(2) pairs thus formed are linked into a supra-molecular chain via C-H⋯O(water) contacts.
