Structural Variation and Preference in Lanthanide-pyridine-2,6-dicarboxylate Coordination Polymers

© 2017 American Chemical Society. Ten lanthanide coordination polymers were designed and synthesized using pyridine-2,6-dicarboxylic acid (H 2 pdc) and two different heating techniques (conventional and microwave): [Ln(pdc)(H 2 O) 4 ] 3 ·3Cl {Pa3; Ln = Pr (I), Nd (II), Sm (III), Eu (IV), and Gd (V)}...
