Abstract
The [Ag-3(mu(3)-eta(2)-C=CPh)(2)(dppm)(3)](+) complex {dppm = bis(diph enylphosphino)methane} was prepared by reacting [(RC=C)Ag](infinity), with dppm in CH2Cl2. The X-ray crystal structure of [Ag-3(mu(3)-eta(2) -C=CPh)(2)(dppm)(3)]Cl . 4Et(2)O . H2O has been determined. The comple x hasan isosceles triangular array of Ag atoms and with two asymmetric phenylacetylide caps. The intramolecular Ag(I) ... Ag(I) separations are 2.866(2) and 2.983(1) Angstrom. Extended-Huckel molecular-orbital calculation reveals that the HOMO comprises prises of contributions fr om Ag(I) and phenylacetylide whereas the LUMO is largely the pi of ph enylacetylide. The complex shows a solid-state emission at 555 nm with a lifetime of 0.4 mu s at room temperature.
