Crystal Structure of Lanthanide Salts with 2,4-Dichlorophenoxyacetic Acid

Year: 2024

Type: article

Abstract: Compounds of three types, [LnL3(C2H5OH)] (Ln = Nd (I), Sm (II), Eu (III)), [LnL3(H2O)] (Ln = = Gd (IV), Tb (V)), and [DyL2(NO3)(C2H5OH)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.
