Synthesis, structure and Magnetic Property of a New Neodymium-Adipate Coordination Polymer with Large Guest Molecules

A new lanthanide-adipate coordination polymer, Nd2(ad)3(H2O)4](H2ad)_4H2O}n (1) (H2ad = adipic acid), has been hydrothermally synthesized and structurally characterized by X-ray single crystal structure analysis, elemental analysis, infrared spectrum, thermogravimetric analysis and temperature-dependent magnetic susceptibility. The three-dimensional structure of compound 1 is based on edge-sharing NdO8(H2O)2 polyhedron chains, which were interconnected by twisted or extended carbon chains of the adipate ligands in [010] and [001] directions, respectively. The network contains large channels with adipic acid and lattice water acting as guest molecules. Above 50 K, the magnetic susceptibility data of 1 can be fitted to the Curie-Weiss law with teta = - 41.0 K and c = 3.52 emu Kmol-1.
