| Abstract: | Chemistry of Polyfunctional Molecules. 124. Silver(I) Complexes Containing the Ligands Bis(diphenylphosphanyl)amine, -amide and Tris(diphenylphosphanyl)amine Bis(diphenylphosphanyl)amine HN(PPh2)2 ( 1 ) reacts with AgCl to the complex HN(PPh2AgCl)2 ( 5 ) for which in the solid state the cluster structure Ag4Cl4[HN(PPh2)2]2 is assumed. Reaction of 5 with LiN(PPh2)2 ( 2 ) gives the known [N(PPh2AgPh2P)2N] ( 8 ) and the new complex [Ag(μ—Ph2PNPPh2)2(μ—Ph2PNHPPh2)Ag] · dioxane ( 7 · dioxane). The compound 7 · dioxane has been characterized by X-ray diffraction. The molecules are found to contain a bicyclo[3.3.3]undecane-type structure with trigonal planar coordinated silver atoms, which are separated by 281,6(1) pm. The dioxane is bound via H-bridge bond to the NH group of the coordinated HN(PPh2)2. Treatment of 8 with ClPPh2 yields N(PPh2AgCl)3 ( 12 ), which has also been obtained by the reaction of N(PPh2)3 ( 3 ) with silver chloride. All the compounds have been characterized, so far as possible, by IR, Raman, 1H NMR, 31P{1H} NMR, 13C{1H} NMR and mass spectroscopy. |
