摘要：
Two lanthanide(Ⅲ) coordination complexes [Ln₂(pya)₆]n (Ln = Pr (1) and Nd (2); pya = pyridine-2-carboxylate) were prepared by hydrothermal reaction. The crystal structures were determined by X-ray crystal diffraction and both of two coordination complexes are isostructures. The complexes form a one-dimensional chain polymer with a tridentate carboxylato-bridged (μ₂-η²:η¹-bridging coordination mode). In both structures, intermolecular C—H···O hydrogen bonds link the molecules, forming a supramoleular network structure. The nearest Ln···Ln is 3.956(1) Å of 1 and 3.946(2) Å of 2, respectively.
