A new two-dimensional Cd(II) coordination polymer, [Cd(dtb)(CH3OH)] n (H2DTNB = 5,5'-dithiobis(2-nitrobenzoic acid), has been synthesized by solvothermal method, and characterized by elemental analysis, IR and single-crystal X-ray diffraction analysis. The complex crystallizes in the orthorhombic Pbca space group, with a = 15.1365(19), b = 7.6198(10), c = 31.761(4) Å, b = 90°, V = 3663.2(8) Å3, Z = 8, Mr = 538.77, D c = 1.954 g/cm3 and F (000) = 2128. The final R = 0.040 and wR = 0.0866 for 3603 observed reflections with I > 2s( I ). In the complex, the Cd(II) ion is coordinated with six oxygen atoms from four carboxylate groups of distinct DTNB ligands and one methanol molecule. The adjacent Cd centers are interconnected by the flexible carboxylate ligand to form a two-dimensional (2D) structure.
