Novel Single- and Double-Layer and Three-Dimensional Structures of Rare-Earth Metal Coordination Polymers: The Effect of Lanthanide Contraction and Acidity Control in Crystal Structure Formation.
Lanthanide atom sizes (the lanthanide contraction) directly control the type of structure formed by the coordination of a single multidentate ligand, 3,5-pyrazoledicarboxylic acid (H(3)pdc). Single-layer, double-layer ([Eu(2)(Hpdc)(3)(H(2)O)(6)], see picture), and three-dimensional networks were found. Control of the reaction pH plays a key role in the structure formation in this system.
