Synthesis and Crystal Structure of a Heterotetranuclear Complex: [Et 4 N] 2 [Pd 2 Ag 2 ( μ - dppm ) 2 ( i -mnt) 4 ]·2DMF·MeCN.

A heterotetranuclear complex, [Et4N]2[Pd2Ag2(μ-dppm)2(i-mnt)4]·2DMF·MeCN, was synthesized by reaction with [Ag2(μ-dppm)2(MeCN)2](SbF6)2and [Et4N]2[Pd(i-mnt)2] (i-mnt is 2,2-dicyanoethylene-1,1-dithiolate) as components and characterized by elemental analysis, IR,1H NMR,31P NMR, and UV-vis spectra. Structure of the complex was determined by X-ray analysis. The results of structural analysis show that not only the weakly coordinated acetonitrile molecules of the [Ag2(μ-dppm)2(MeCN)2]2+unit were substituted, but also the skeleton of it was changed, which is different from the complexes by the self-assembly with [Ag2(μ-dppm)2(MeCN)2](SbF6)2and some metal thiolates as components.
