Two　dipalladium　complexes　[(bpy)(2)Pd-2(NO3)(2)](NO3)(2),　[(dmbpy)(2)Pd-2(NO3)(2)](NO3)(2)　(bpy=2,2-bipyridine,　dmbpy=4,4＇　-dimethyl-2,2-bipyridine)　were　used　as＂clips＂to　coordinate　with　ditopic　pyrazolate　ligands　(HL1,　HL2),　leading　to　the　formation　of　[Pd2L2](2-)　-type　dinuclear　coordination＂clips＂with　strong　intramolecular　Pd(II)center　dot　center　dot　center　dot　Pd(II)　bonding　interaction　through　a　spontaneous　deprotonation　of　the　pyrazole　ligands　in　aqueous　solution.　Such　well-defined　complexes　C1　similar　to　C4　have　been　characterized　by　single-crystal　X-ray　diffraction　analysis,　elemental　analysis,　H-1　and　C-13　NMR,　electrospray　ionization　mass　spectrometry　(ESI-MS)　and　IR　spectroscopy.　Furthermore,　all　these　clip-like　dipalladium(II)　complexes　exhibited　highly　catalytic　activities　towards　Suzuki-coupling　reaction　under　mild　conditions.　CCDC:　2060495,　C1　center　dot　2NO(3)(-).
