A novel 3D (4,5,14)-connected layer-pillared metal-organic framework containing rare planar hexnuclear cadmium(II) clusters

A novel 3D layer-pillared metal-organic framework of [Cd-3(IDC)(BDC)(1.5)(H2O)](n) (1). (H3IDC = imidazole-4,5-dicarboxylic acid. H2BDC = 1.4-benzenedicarboxylic acid) was obtained by hydrothermal reaction, which contains rare planar hexnuclear Cd(II) cluster structural units and represents an unprecedented trinodal (4,5,14)-connected topology network. Furthermore, the thermal stability and luminescent property of I have also been examined. (C) 2012 Elsevier B.V. All rights reserved.
