Self‐assembled binuclear complexes of Pd 2 L′ 2 L 2 and Pd 2 L 4 type formulations have been achieved by combining the cis ‐protected palladium(II) component i. e., [PdL′] 2+ (where L′ stands for tmeda) and naked palladium(II) separately with a 3‐pyridyl appended non‐chelating bidentate ligand, L under suitable conditions. Supramolecular fusion of the Pd 2 L 4 and PdL′ 2 type complexes have been demonstrated that provided the corresponding Pd 2 L′ 2 L 2 type complex. One pot synthesis of the binuclear Pd 2 L′ 2 L 2 type complex is achieved by combining palladium(II), L′ and L at equimolar ratio, however, along with an unidentified trap. The crystal structure of a Pd 2 L 4 type complex confirmed the binuclear architecture of the cage. Intermolecular H‐bonding and π‐π stacking interactions are analyzed from the crystal structure and the extended intermolecular interactions apparently generated a grid pattern.
