A　series　of　clip-shaped　cationic　molecular　corners　C1∼C4　(C1　=　[(bpy)2Pd2(L1)2]2+,　C2　=　[(dmbpy)2Pd2(L1)2]2+,　C3　=　(bpy)2Pd2(L2)2]2+,　C4　=　(dmbpy)2Pd2(L2)2]2+,　bpy　=　2,2-bipyridine,　dmbpy　=　4,4′-dimethyl-2,2-bipyridine)　were　synthesized　through　dipalladium　complexes　[(bpy)2Pd2(NO3)2](NO3)2,　[(dmbpy)2Pd2(NO3)2](NO3)2and　bifunctional　pyrazole　ligands　4-(3,4-dimethoxyphenyl)-3,5-dimethyl-1H-pyrazol　(HL1)　and　4,4′-(5-(1H-pyrazol-4-yl)-1,3-phenylene)dipyridine　(HL2).　Complexes　C1∼C4　were　characterized　by　1H　and　13C　NMR,　electrospray　ionization　mass　spectrometry　(ESI-MS),　elemental　analysis,　and　IR　spectroscopy.　The　X-ray　diffraction　analysis　of　C1·2NO3-　revealed　a　Pd2　dimetallic　clip-shaped　structure　which　was　synthesized　by　two　bifunctional　ligands　doubly　bridged　by　the　[(bpy)Pd]2dimetal　units.　Additionally,　all　of　the　complexes　with　NO3-as　counter　anions　exhibited　high-efficiency　catalytical　performance　in　the　Suzuki-coupling　reaction　attributed　to　the　tunable　impact　and　weak　dinuclear　Pd(II)···Pd(II)　intramolecular　bonding　interaction.　©　2021　Fujian　Institute　of　Research　of　the　Structure　of　Matter.　All　rights　reserved.
