3-Phenyl-2-(piperidin-1-yl)-3,5,6,8-tetra-hydro-4H-thio-pyrano[3',4':2,3]thieno[5,4-d]pyrimidin-4-one.


ABSTRACT: In the title compound, C(20)H(21)N(3)OS(2), the piperidinyl ring has a distorted chair conformation. Weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers. The crystal packing exhibits short inter-molecular S⋯S distances of 3.590 (2) Å.
