Self-assembly of a Cd(II) coordination polymer with the 3,5L2 topology: Synthesis, structure, and properties
A new cadmium(II) coordination polymer, [Cd(ntdc)(dps)H2O](n), was synthesized using 3-nitro-thiophene-2,5-dicarboxylic acid (H(2)ntdc) and 4,4 '-dipyridylsulfide (dps) as organic linkers. In the complex, adjacent Cd2+ ions are linked by ntdc(2-) anions adopting a new coordination mode to form a one-dimensional (1D) [Cd(ntdc)](n) chain. Then dps ligands further expand the 1D chain into a corrugated two-dimensional (2D) layer network by linking neighboring Cd2+ ions. Topologically, the 2D network can be rationalized to a 3,5-connected 3,5L2 topology. Moreover, solid state properties such as thermogravimetric analysis and photoluminescent property were also investigated.
