title: A dimeric layered structure of a 4-oxo-4,5-dihydro-1H-pyrazolo[3,4-d]pyrimidine compound.
abstract: The title compound, 6-methylsulfanyl-1-(3-phenylpropyl)-4,5-dihydro-1H-pyrazolo[3,4-d]pyrimidin-4-one, C(15)H(16)N(4)OS, crystallizes in space group Pbca, with two molecules of similar structure in the asymmetric unit. The molecular structure shows the absence of intramolecular stacking in the crystalline state, as indicated by earlier (1)H NMR analysis in solution. In addition, the crystal packing reveals the formation of a layered structure, due mainly to intermolecular N[bond]H...O[double bond]C hydrogen bonding and arene-arene interactions.
