The title compound (C12H15NO13S, Mr = 413.31) was synthesized by the nitration of napthalene- 1,4-dicarboxylate acid in mixed nitric and sulfuric acids. It crystallizes in monoclinic,space group P21/c with a = 8.100(1), b = 24.369(3), c = 8.634(1)(A),β= 105.380(2)°, V= 1643.1(4)(A)3, Z= 4, Dc = 1.671 g/cm3, F(000) = 856, μ(MoKα) = 0.273 mm-1, T= 294(2) K, the final R =0.0400 and wR = 0.1021 for 2866 observed reflections with 1 > 2σ(Ⅰ). In this crystal there exist a number of H-bonds which link the molecules to form a three-dimensional infinite network structure.The thermal decomposition of the title compound was investigated by using TG-DTG and DSC techniques.
