The nearly planar molecule of the fungal metabolite infectopyrone, C 14 H 16 O 5 , with an r.m.s. deviation of 0.040 (2) A ˚from the plane through all atoms, is linked tail-to-tail by strong O-HÁ Á ÁO hydrogen bonds into dimers. Weaker C-HÁ Á ÁO hydrogen bonds link the pyran-2-one 'head' groups.

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.
