✦ Synopsis

In the title compound, C 11 H 18 N 2 O 2 S, the dihedral angle between the thiophene ring and the mean plane of the puckered imidazolidine ring is 85.0 (2) . Adjacent molecules are linked by pairs of inversion-related O-HÁ Á ÁN hydrogen bonds, leading to a chain structure.

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.

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.
