✦ Synopsis


The main features of the crystal structure of the title radical, C 13 H 7 D 16 N 2 O 2 , are N-HÁ Á ÁO and C-HÁ Á ÁO hydrogen bonds, which are responsible for the formation of chains of molecules in the [001] direction.

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.
