Abstract
We report the crystal structure of the unusual imide thylidene)bis(2,2 -dimethyl-1,3-dioxane-4,6-dione), C14H15NO8, which contains two Meldru m's acid (dioxanedione) substituents. The geometry of the imide moiety shows the effects of delocalization of the N-atom lone pair, while th e overall conformation of the molecule is associated with the formatio n of strong intramolecular hydrogen bonds.
