Synthesis of luminescent trinuclear silver(I) acetylides of bis(diphenylphosphino)methane and bis(diphenylphosphino)-n-propylamine. X-ray crystal structures of [Ag-3(mu-dppm)(3)(mu(3)-eta(1)-C equivalent to C-C6H4-NO2-p)](2+) and [Ag-3(mu-dppm)(3)(mu(3)-eta(1)-C equivalent to C-C6H4-NO2-p)(2)](+)

A series of soluble trinuclear silver(I) complexes containing monocapped and bicapped acetylides, [Ag-3(LL)(3)(mu(3)-eta(1)-C=CR)](2+) and [Ag-3(LL)(3)(mu(3)-eta(1)-C=C-C6H4-NO2-p)(2)](+) [LL=[(C6H5)(2)P](2)-CH2 (dppm), [(C6H5)(2)P](2)(NPr)-Pr-n((PrPNP)-Pr-n)], have been synthesized. The X-ray crystal structures of [Ag-3(mu-dppm)(3)(mu(3)-eta(1)-C=C-C6H4-NO2-p)](2+) and [Ag-3(mu-dppm)(3)(mu(3)-eta(1)-C=C-C6H4-NO2-p)(2)](+) have been determined.
