2D Ln^III(Nd/La)‐Ag^I Heterometallic and Tm^III Homometallic Coordination Polymers Based on Pyridine Dicarboxylate ­Ligands

Abstract

Abstract. Two 2D 4d-4f heterometallic coordination polymers, (2); H 2 Py26DC = pyridine-2,6-dicarboxylic acid], and one 2D lanthanide homometallic coordination polymer, [Ln(Py25DC)(ox) 0.5 (H 2 O) 2 ] [Ln = Tm (3); H 2 Py25DC = pyridine-2,5-dicarboxylic acid; ox = oxalate], were synthesized and characterized by elemental analysis, IR spectroscopy, thermogravime-

Syntheses, Crystal Structures and Luminescent Properties of a Series of Ag-Ln Coordination Polymers

“…Nd−O bond lengths are ranging from 2.475(4)‐2.538(4) Å, Nd−N1 bond length is 2.608(5) Å, Nd−N2 bond length is 2.615(4) Å and Ag−O bond lengths are ranging from 2.222(5)‐2.487(5) Å. In addition, the synthesis of polymer 2 is similar to that of heterometallic (Nd/La)‐Ag(I) polymers basing on pyridine dicarboxylate ligands, only that there are three lattic water molecules in their asymmetric unit, and no properties are further studied. However the luminescent properties of the polymers are discussed in this paper.…”
