K.-D. Warzecha, J. Neudörfl and A. G. Griesbeck

Abstract: The molecule of the title compound, C₁₁H₁₁NO₄ (alternative name: 4,5-dimethoxy-N-methylphthalimide), a highly fluorescent phthalimide, is essentially planar. In the crystal structure, pairs of molecules form a -stacked head-to-tail dimer with a remarkably short interplanar distance of 3.34 (2) Å.
