Four coordination polymers, namely, {[Co(mu-glu)(nmim)(2)]center dot 2H(2)O)(n) (1), [Cu(mu-glu)(nmim)(2)] (2), [[Zn (mu-glu)(nmim)(2)]center dot 2H(2)O), (3) and [Cd(u-glu)(nmim)21 (4) (glu = glutarate, nmim = N-methylimidazole), have been synthesized and characterized by elemental analysis, IR spectroscopy, thermal analysis and single-crystal X-ray diffraction techniques. Moreover, the photoluminescence properties of 3 and 4 have been investigated. Structural analyses reveal that all the complexes exhibit one-dimensional (10) linear chain structures bridged by the glutarate ligand, which further form 3D supramolecular networks via intermolecular it pi center dot center dot center dot pi, C-H center dot center dot center dot pi and weak hydrogen bonding interactions. In the complexes, the glu ligand adopts the bis-monodentate and bis-bidentate bridging modes through two and four carboxylate oxygen atoms, respectively. The distorted octahedral geometry for complexes 2 and 4 and tetrahedral geometry for complexes 1 and 3 are completed by two nmim ligands. Complexes 3 and 4 exhibit a blue emission in the solid state at room temperature. (C) 2013 Elsevier Ltd. All rights reserved.
