The title compound, C16H20N4OS2, was synthesized by the reaction of 2-benzyl-sulfanyl-5-chloro-acetamido-1,3,4-thia-diazole and piperidine in a 1:2 ratio. The planes of the acetamide and 1,3,4-thia-diazole units are twisted by 10.8 (4)°. The thia-diazole S atom and the acetamide O atom are syn-oriented due to a hypervalent S⋯O inter-action of 2.628 (4) Å. In the crystal, mol-ecules form centrosymmetric dimers via N-H⋯N hydrogen bonds. These dimers are further connected by C-H⋯O inter-actions into (100) layers.
标题化合物C₁₆H₂₀N₄OS₂是由2-苄基硫烷基-5-氯乙酰胺基-1,3,4-噻二唑与哌啶以1:2的比例反应合成的。乙酰胺基和1,3,4-噻二唑单元的平面扭转了10.8(4)°。由于2.628(4) Å的超价S⋯O相互作用，噻二唑的S原子和乙酰胺的O原子呈顺式取向。在晶体中，分子通过N-H⋯N氢键形成中心对称二聚体。这些二聚体通过C-H⋯O相互作用进一步连接成(100)层。
