A new compound of [（H2DTBB）·（CH3CN）]n （1）, （H2DTBB = 2, 2＇-disulfanediyldibenzoic acid）, has been synthesized under the hydrothermal condition and characterized by IR spectroscopy and single-crystal X-ray diffraction. The crystal structure of 1 is of monoclinic, space group C2/c with a = 1.6423（3） nm, b = 1.2785（3） nm, c = 2.1119（4） nm, fl= 109.12~, V= 4.1897（15） nm3, Z = 4. Compound 1 is built from in-situ generated H2DTBB and solvent acetonitrile molecules, and resulting in a three-dimensional supramolecular structure via the interactions of the ...n stacking and the strong hydrogen bonding. Luminescent property and the UV-visible spectrum of the compound have also been investigated.
