A d10 Metal Coordination Polymer Containing a Thiodiphthalic Ligand: Crystal Structure and Luminescent Property

A new two-dimensional metal-organic coordination polymer [Cd-2(2,3,2',3'-sdpa)(H2O)(3)]center dot 2H(2)O (1) were hydro(solvo)thermally synthesized by the reaction of 2,3,2',3'-sulfonyldiphthalic acid (2,3,2,3'-H(4)sdpa) with Cd(NO3)(2)center dot 4H(2)O and characterized by elemental analysis, thermogravimetry, IR and luminescence spectroscopy, and X-ray diffraction. In complex 1, two kinds of cadmium atoms are linked together by anionic sdpa(4-) ligands to form a 2D metal-organic network. The adjacent 2D layers further interact with each other through hydrogen bonds and pi center dot center dot center dot pi interactions to form a 3D supramolecular structure. The luminescence spectra and thermal properties of 1 were also investigated.
