A　series　of　clip-shaped　cationic　molecular　corners　C1　similar　to　C4　(Cl　=　[(bpy)(2)Pd-2(L-1)(2)](2+),　C2　=　[(dmbpy)(2)Pd-2(L-1)(2)](2+),　C3　=　(bpy)(2)Pd-2(L-2)(2)](2+),　C4　=　(dmbpy)(2)Pd-2(L-2)(2)](2+),　bpy　=　2,2-bipyridine,　dmbpy　=　4,4＇-dimethyl-2,2-bipyridine)　were　synthesized　through　dipalladium　complexes　[(bpy)(2)Pd-2(NO3)(2)](NO3)(2),　[(dmbpy)(2)Pd-2(NO3)(2)](NO3)(2)　and　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　similar　to　C4　were　characterized　by　H-1　and　C-13　NMR,　electrospray　ionization　mass　spectrometry　(ESI-MS),　elemental　analysis,　and　IR　spectroscopy.　The　X-ray　diffraction　analysis　of　C1　center　dot　2NO(3)(-)　revealed　a　Pd-2　dimetallic　clip-shaped　structure　which　was　synthesized　by　two　bifunctional　ligands　doubly　bridged　by　the　[(bpy)Pd](2)　dimetal　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)center　dot　center　dot　center　dot　Pd(II)　intramolecular　bonding　interaction.
