| Abstract: A bipyrazolato-bridged tetra-palladium(II) cyclic complex, {[(dmbpy)Pd]2(μ-L)}·(PF6)4·2(C4H10O)·(H2O) ( μ-L=1,2-bis(3,5-dimethyl-pyrazol-4-yl)benzene), was synthesized and characterized by the 1H NMR, element analysis, and its single crystal structure was determined by X-ray diffraction method. It crystallizes in the Tetragonal space group P4/mbm with unit cell parameters: a=2.020 0(1) nm, b=2.020 0(1) nm, c=1.281 4(1) nm, and V=5.228 5(5) nm3, Z=2, R=0.047 8, wR=0.083 9. The crystal structure revealed that two [(dmbpy)Pd]2 moieties were bridged by two bipyrazolate ligands to form a tetra-palladium(II) cyclic complex. The Pd…Pd separation within the complex is 0.315 5(1) nm, indicat-ing weak interaction. CCDC: 645322. |
