2-(2,4-Dihydroxybenzoyl)benzoic acid

Abstract

In the title structure, C14H10O5, the angle between the planes formed by the 2,4‐di­hydroxy­benzoyl and o‐benzoic acid moieties is 87.12 (4)°. In addition to an intramolecular O—H⋯O hydrogen bond, intermolecular O—H⋯O hydrogen bonds (H⋯O = 1.76 and 1.89 Å) connect mol­ecules to form a two‐dimensional network parallel to (10).

“…The title compound is currently being used as a starting material for synthesis of new chelating ligands. There have been several derivatives of resorcinol published in the literature (Fronczek et al, 1987;Kokila et al, 1992;Liebich, 1979;Li et al, 2005;van Rooyen & Breytenbach, 1988). The compound most similiar to (I) (Kokila et al, 1992) has two acetyl groups found in the 4 and 6 positions.…”
