A novel heterometallic diPd II –diCu II grid‐chain, {[(bpy) 4 Pd 4 Cu 2 L 4 ](NO 3 ) 4 } n ( 2 ; bpy=2,2′‐bipyridine), was synthesized through a programmable self‐assembly approach from the molecular corners [(bpy) 2 Pd 2 (HL)(L)](NO 3 ) ( 1 ) as linkers with Cu II nitrate by using the bifunctional H 2 L ligand featuring primary (pyrazole) and secondary (benzoic acid) groups. Structural analysis revealed that 1D structure 2 consists of one [Cu 2 (O 2 CPh) 4 ] n unit as a bridge and two [(bpy) 2 Pd 2 L 2 ] n corners. Additionally, the catalytic effect of the heterometallic synergy on the Suzuki coupling reaction by using 2 was further explored.
