Maleic anhydride, redetermination at 130 K

M. Lutz

Abstract: The X-ray crystal structure of the title compound (2,5-furandione), C₄H₂O₃, was redetermined at 130 (2) K. The C=C double bond, previously reported to be unusually short, was accurately measured as 1.3322 (9) Å and thus proved to be fairly standard. The relatively high melting point of the compound is attributed to the intermolecular dipole-dipole interactions between carbonyl groups.
