2-(2-Carboxyethyl)-1,3-dioxoisoindoline-5,6-dicarboxylic acid methanol monosolvate

S. Khorasani and M. A. Fernandes

Abstract: In the title compound, C₁₃H₉NO₈·CH₃OH, the main molecule possesses three carboxylic acid groups, which are asymmetrically distributed around the molecule core. This results in hydrogen-bonding motifs ranging from a chain to various rings. The combination of the chain motif together with a carboxylic dimer R₂²(8) ring motif creates a ribbon of molecules propagating along the c-axis direction. A second ribbon results from the combination of the chain motif together with a methanol solvent molecule and carboxyl-containing R₄⁴(12) ring motif. These two ribbons combine alternately, forming a hydrogen-bonded layer of molecules parallel to (2 $\overline{1}$ 0).
