Acta Crystallographica Section E, 63(11), 1-9.https://hdl.handle.net/10289/2686The sterically crowded title compound, C₁₄H₁₂O₄, crystallizes as centrosymmetric hydrogen-bonded dimers involving the carboxyl groups. The naphthoquinone ring system is folded by 11.5 (1)° about a vector joining the 1,4-C atoms, and the quinone O atoms are displaced from the ring plane, presumably because of steric interactions with the bulky substituent.application/pdfenThis is an electronic reprint as authorised by the publisher.organic compoundchemistryJournal Articledoi:10.1107/S1600536807048131
