摘要：

The crystal and molecular structure of 2,6-dihydroxybenzoic acid has been determined by single crystal X-ray diffraction. The crystals are monoclinic with a = 5.4084(5), b = 5.2240(7), c = 22.986(4) angstrom, beta = 94.69(3)-degrees, space group P2(1)/c, Z = 4, V = 647.27(16) angstrom3, d(c) = 1.58 Mg m-3. The acid crystallizes as hydrogen bonded carboxylic dimers which pack to generate a herringbone motif of the type typically encountered in polycyclic aromatic compounds.
