New palladium polymeric compounds containing novel tetradentate halogen-substituted 6Me2bpX2- ligands (6Me2bpX2- = 1,2-bis(6-methylpyridine-2-carboxamide) halobenzene dianion, X = F for 4, Cl for 5) were constructed by non-classical C-H⋯X-C interactions, and the novel catalyst 5 was used to carry out Suzuki coupling reactions with aryl iodides and aryl boronic acids under mild conditions.
