Diaquatris(4-pyridylcarboxylato)neodymium(III)

T. Shao and H.-T. Zhang

Abstract: The isonicotinate (4-pyridylcarboxylate) ligand was used to synthesize the title compound, [Nd(C₆H₄NO₂)₃(H₂O)₂]. It has a one-dimensional chain structure. The Nd atom lies on a crystallographic twofold axis. The Nd^III center is in an infinite chain, coordinated by four carboxylate O atoms of bridging isonicotinate groups, two carboxylate O atoms of the chelating isonicotinate group, and two water molecules. Weak interactions between pyridine H and N atoms generate a three-dimensional framework.
