The molecule of the title compound, C 21 H 26 O 11 , possesses normal geometric parameters. Intermolecular C-HÁ Á ÁO hydrogen bonds link adjacent molecules to form onedimensional chains along the crystallographic a axis.
The title compound, C~26~H~26~N~2~O~7~, is a thiamidine derivative. Geometric parameters are in the usual ranges. The crystal packing is stabilized by a classical N—H...O hydrogen bond, several weak C—H...O hydrogen bonds and a π–π stacking interaction.
In the title compound, C 17 H 17 N 3 OS 2 , the fused thiophene and pyrimidine rings are almost coplanar. The amino group is involved in both intramolecular and intermolecular hydrogen bonds, the latter linking the molecules into a centrosymmetric dimer.
The title compound, C 9 H 12 N 2 O 3 , was synthesized by the reaction in ethanol of ethane-1,2-diamine and 3-[bis(methylthio)methylene]-6-methyl-3,4,5,6-tetrahydro-2H-pyran-2,4dione. Two intramolecular N-HÁ Á ÁO hydrogen bonds induce a high degree of planarity.
In the title molecule, C~11~H~11~FN~2~OS, conformational disorder is observed in the tetrahydropyrimidine ring and both components adopt half-chair conformations. In the crystal structure, the molecules are linked by C—H...O and N—H...S hydrogen bonds, forming a sheet-like structure parallel to the
