abstract	A series of lanthanide pimelates [Sm(phen)(Hpim)(pim)](n)center dot 1.5nH(2)O (1, phen = 1,10-phenanthroline, H(2)pim = pimelic acid), and [Ln(phen)(pim)](n)center dot nClO(4)center dot nH(2)O [Ln = Gd (2a), Tb (2b), Er (2c)] have been hydrothermally synthesized and characterized structurally by elemental analysis, IR spectroscopy, thermogravimetric analysis and PXRD. Compound 1 contains 1-D neutral [Sm(phen)(Hpim)(pim)](n) chain that is constructed by the linkages of [Sm(phen)] ions and pim(2-) /Hpim(-) ligands, while compounds 2a-c contain 1-D cationic [Ln(phen)(pim)(+)](n) chain with ClO4- ion as counterion. Although a lot of lanthanide coordination polymers were obtained with aliphatic dicarboxylic acids, they usually show neutral frameworks. Compounds 2a-c provide the only examples of cationic lanthanide pimelate frameworks decorated by phen chromophores. The photoluminescent properties of 1 and 2b-c, and magnetic properties of all compounds have been studied. (C) 2017 Elsevier B.V. All rights reserved.
