摘　　要：A novel pyrazolato-bridged di-palladium髤 complex, {[(phen)Pd(Me2Pz-H)]2(μ-Me2Pz)}(NO3)(BF4)2(MeCN)(Me2Pz-H=3,5-dimethyl pyrazole; μ-Me2Pz=3,5-dimethyl pyrazolate), was synthesized and characterized by the element analysis and single crystal X-ray diffraction. It crystallizes in the monoclinic space group P21/c with unit cell parameters: a=1.131 6(3) nm, b=1.858 5(4) nm, c=2.127 0(5) nm, β=90.037(4)°, and V=4.473 2(18) nm3, Z=4, R=0.043 3, wR=0.123 7. The X-ray crystal structure analysis revealed that two Pd髤 atoms were bridged by one pyrazolate, and the other two pyrazole molecules were coordinated to the two Pd髤 atoms, respectively. The Pd...Pd separation within the complex is 0.349 2(1)nm, indicating quite weak interaction.

It crystallizes in the monoclinic space group P21/c with unit cell parameters： a=l.131 6（3） nm, b=1.858 5（4） nm, c=2.127 0（5） nm,/3=90.037（4）°, and V=4.473 2（18） nm^3, Z= 4, R=0.043 3, wR=0.123 7. The X-ray crystal structure analysis revealed that two Pd（Ⅱ） atoms were bridged by one pyrazolate, and the other two pyrazole molecules were coordinated to the two Pd（Ⅱ） atoms, respectively. The Pd…Pd separation within the complex is 0.349 2（1）nm, indicating quite weak interaction. CCDC： 290065.
