A novel (3,4,5)-connected pillared-bilayer CdII-network bearing unattached self-penetrating prototype in a co-ligand system

The μ5-dpstc4−anions (H4dpstc = 3,3′,4,4′-diphenylsulfonetetracarboxylic dianhydride) link CdII centers to generate a 2D bilayer with two kinds of channels, further, 2-dpe pillars (2-dpe = trans-1,2-di(2-pyridyl)ethylene) extend such 2D bilayer into a novel (3,4,5)-connected trinodal network [Cd2(dpstc)(2-dpe)(H2O)3]n, which features unattached self-penetrating prototype and three types of channels in one direction. In addition, the luminescent property and thermal stability of the complex 1 have been also discussed.
