A heterometallic organic framework {Pb[Pd(bpydc)Cl 2 ]DMF} n ( 1 ) (H 2 bpydc = 2,2′‐bipyridine‐5,5′‐dicarboxylic acid) was synthesized via a one‐pot solvothermal method and characterized using thermogravimetric analysis, X‐ray photoelectron spectroscopy as well as powder and single‐crystal X‐ray diffraction. The crystal structure of 1 indicates that, in metalloligand Pd(bpydc)Cl 2 , every Pd atom adopts a square planar coordination mode with two chloride ions and two nitrogen atoms from bpydc, and the carboxyl groups of Pd(bpydc)Cl 2 connect Pb atoms to form a one‐dimensional chain along the crystallographic a ‐axis, which is interlinked via metalloligands to form a two‐dimensional layer structure. This complex is highly active, stable and recyclable as a catalyst for the Suzuki–Miyaura and Heck reactions of a wide range of aryl halides including electron‐rich and electron‐poor aryl iodides/bromides, affording the corresponding products in good to excellent yields.
