In the title compound, C15H17N3OS2, the piperidine ring adopts a chair conformation. Weak inter-molecular C - H⋯O hydrogen bonds link the mol-ecules into chains along the c axis and further stability is provided by offset π-π stacking inter-actions [centroid separations = 3.73 (2)-3.78 (2) Å] involving the aromatic rings. © Inter...
