Abstract
- A series of lanthanide pimelates [Sm(phen)(Hpim)(pim)] n ·1.5nH 2 O ( 1 , phen = 1,10-phenanthroline, H 2 pim = pimelic acid), and [ Ln (phen)(pim)] n ·nClO 4 ·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 ClO 4− 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. [ABSTRACT FROM AUTHOR]
