Abstract
The reaction of [Ag(dppm)(NO 3] 2 with sodium phenylacetate and dppm in THF at room temperature gave rise to the silver complexes [Ag(dppm)(O 2CCH 2Ph)] 2 ( 1) and [Ag 2(dppm) 3](NO 3) 2 ( 2), respectively. Their crystal structures have been determined by single crystal X-ray diffraction analysis. Complex 1 is binuclear with a silver-silver separation of 3.080 Å and bridged by two dppm ligands. The cation in complex 2 possesses a Ag 2P 6 core with AgAg distance of 2.987 Å and the silver atoms are each coordinated by three phosphorus atoms in an ideal trigonal-planar environment. Their IR, Raman, 1H and 31P NMR spectroscopic properties are also reported.
