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 [Cd3(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 1 have also been examined.

An unprecedented 3D (4,5,14)-connected layer-pillared metal-organic framework of [Cd3(IDC)(BDC)1.5(H2O)]n (1) (H3IDC = imidazole-4,5-dicarboxylic acid, H2BDC = 1,4-benzenedicarboxylic acid) containing rare hexnuclear Cd(II) clusters has been hydrothermally synthesized. Photoluminescent measurement illustrates 1 emits strong luminescence at 465 nm.Figure optionsDownload as PowerPoint slideHighlights
