The compound 2,2’-dithiodibenzoic acid-acetonitrile compound [(H2DTBB) · (CH3CN)] n (1) and H2DTBB = 2,2’-dithiodibenzoic acid were synthesized by hydrothermal reaction. Its structure was characterized by IR and X-ray single crystal diffraction. The complex belongs to monoclinic system with C2 / c space group with a = 1.6423 (3) nm and b = 1.2785 (3) ) nm, c = 2.1119 (4) nm, β = 109.12, V = 4.1897 (15) nm3, Z = 4. The compound is synthesized from o-mercaptobenzoic acid by in-situ synthesis of H2DTBB and the solvent molecule of acetonitrile, and the three-dimensional supramolecular structure is formed by intermolecular π stacking and hydrogen bonding. The fluorescence properties and UV-visible diffuse reflectance spectra of the compounds were also determined.
