摘　　要：二-（二苯基膦）甲烷（dppm）是一种易与金属形成多核络合物的有机膦配体。我们用dppm作为配体合成了一系列银的多核络合物,并对其结构进行了研究。本文报导了其中一个双核化合物[Ag₂（dppm）₂（Py）₂（μ-Cl）]ClO₄的合成及晶体结构、分子结构的测定。The title complex was prepared, and its crystal and molecular structures were characterized by XRD method. The crystal beongs to orthorhombic system, space groupP2_12_12_1, with dimensions: a=13.41(7), b=20.10(5), c=21.43(5)(?);V=5776.2(?)~3; Z=4; Dc=1.469g/cm^3. Two silver atoms in the cation of the title complex are llinked by a Cl bridge and two dppm ligands through their P atoms. Each silver atom is asymmetrically four-coordinated. The skeleton of cation Ag_2P_4C_2 forms a distorted octacyclic ring, with two terminal pyridines at the same side as Cl atom-a W frame structure.
