2'-Amino-3,6-dihydroxyxanthene-9-spiro-1'-isoindolin-3'-one monohydrate

D.-X. Wang and G.-H. Wu

Abstract: The title compound, C₂₀H₁₄N₂O₄·H₂O, was synthesized by the reaction of fluorescein and hydrazine hydrate in ethanol. In the crystal structure, the organic molecules are linked into extended two-dimensional networks by intermolecular hydrogen bonding. Additional face-to-face - stacking interactions between the phenolic benzene rings in two adjacent molecules [centroid-to-centroid separation = 3.773 (3) Å] link the molecules into a three-dimensional framework.
