Abstract
The asymmetric unit of the racemic form of the title compound, C(12)H(15)NOS, contains four crystallographically independent molecules. The olefinic bond connecting the 2-thienyl and 1-azabicyclo[2.2.2]octan-3-ol moieties has Z geometry. Strong hydrogen bonding occurs in a directed co-operative O-H...O-H...O-H...O-H R(4)(4)(8) pattern that influences the conformation of the molecules. Co-operative C-H...pi interactions between thienyl rings are also present. The average dihedral angle between adjacent thienyl rings is 87.09 (4) degrees.
