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

The mu(5)-dpstc(4-)anions (H(4)dpstc =3,3',4,4'-diphenylsulfonetetracarboxylic dianhydride) link Cd-II 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 [Cd-2(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. Crown Copyright (C) 2011 Published by Elsevier B.V. All rights reserved.
