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.
