A. J. Kresge, A. J. Lough and Q. Meng

Abstract: The structure of the title compound, C₈H₆O₃, was determined in order to resolve a long-standing uncertainty as to whether this compound or its isomer, 2,3-dihydro-3-hydroxybenzo[b]furan-2-one, is the solid substance with a melting point of 381  K, prepared by a variety of methods over a number of years. The molecules form infinite (O-HO) hydrogen-bonded chains, through 2₁ axes in the b direction, with an OO distance of 2.7095  (14)  Å.
