The first two three-dimensional (3D) pillared metal–olsalazine complexes, namely [Co(osa)0.5(bim)0.5(H2O)] (1) and [Cd(osa)0.5(bim)0.5(H2O)] (2) (H4osa = 3,3-azo-bis(6-hydroxybenzoic acid), bim = 1,4-bis(imidazol-1-yl)butane) have been hydrothermally synthesized and further characterized by single-crystal X-ray diffraction, powder X-ray diffraction, elemental analysis, IR spectra and TG analyses. Compounds 1 and 2 are isostructural, and their frameworks are composed of infinite rod-shaped secondary building units (SBUs) that are bridged by osa ligands to form 2D layers, which are further pillared by bim ligands in the third dimension. To the best of our knowledge, it is the first time that 3D pillared-layer frameworks involving infinite rod-shaped SBUs have been obtained in the realm of metal–olsalazine complexes. The magnetic property of 1 and photoluminescence of 2 have also been investigated.
The first two 3D pillared metal–olsalazine complexes, based on infinite rod-shaped secondary building units, are reported, which also represent the first 3D coordination polymers constructed from the mixed olsalazine and N-containing ligands and exhibit good magnetic or luminescent properties.Figure optionsDownload as PowerPoint slideHighlights
