Description
Summary:Compounds of three types, [LnL 3 (C 2 H 5 OH)] (Ln = Nd ( I ), Sm ( II ), Eu ( III )), [LnL 3 (H 2 O)] (Ln = Gd ( IV ), Tb ( V )), and [DyL 2 (NO 3 )(C 2 H 5 OH) 2 ] ( VI ), were obtained by reactions of lanthanide nitrate with NaL (L – = 2,4-dichlorophenoxyacetate anion) in ethanol. The composition and structure of complexes I – VI were investigated by elemental and thermogravimetric analysis, IR spectroscopy, and X-ray diffraction (nos. 2311578 ( I ), 2311579 ( II ), 2311580 ( III ), 2311581 ( IV ), 2311582 ( VI )). All compounds have a one-dimensional polymer structure in which metal atoms are connected by bridging carboxylate groups. The π–π interactions and intermolecular contacts between the chains give rise to a three-dimensional supramolecular structure.
