英文摘要	A new polynuclear silver complex with bridging diphorsphine ligand has been synthesized and characterized by :single cryatsl X-ray diffraction method The compound crystallizes in the triclinic space group P1 with a=1.27489, b=1.34715, c=1.47015 angstrom; alpha=59.747, beta=63.949, gamma=70.196 degrees, V=1936.9 angstrom(3). The simplest formularis [Ag(4)center dot dppe)(3)(NO(3))(4)], M(r)=1874.79, D(c)=1.607 g center dot cm(-1), Dm=1.62 g center dot cm(-3), mu(MoKa)=11.69 cm(-1), F(000)=942. The structure was solved by conventional heavy-atom techniques and refined by full-matrix least squares to give discrepany indices of R=0.048 and RW=0.060(W=1/[sigma(Fo)(2)+(PW(T)*Fo)(2)+QW(T)]-Fo) for 5052 reflections. An empirical absorption correction program DIFABS was performed. Silver atoms are linked by bridging ligands of dppe and nitrate, forming a network extending in space. Each structural unit contains two binuclear subunits, of which silver atoms are bridged by nitrates. The two subunits are connected by one dppe ligand. Silver atoms are not equivalent in subunit and one of the nitrates functions not only as a monodentate bridging ligand, but also as an asymmetric bidentate chelating lingand. All coordinate configurations of silver are shown as distorted tetrahedron.
