Results and Discussion ,[object Object],► The PNP ligand reacted with Rh(I) metal [Rh( μ – Cl)(C 2 H 4 ) 2 ] 2 in toluene at room temperature to give [RhCl(PNP)] 1a complex, which was isolated as a green crystalline solid. ► Complex 1a was converted to rhodium triflate 1b by treatment with AgOTf ► The same reaction conditions were used to prepare complexes 2a , 2b , and 2c .

Molecular Structure of 1a Complex ► The Rh–P lengths are shorter than those of Rh–Cl. ► X-ray structure of 1a , adopts a distorted square planar geometry.

[object Object],Synthesis of Copper(I) Complex ► X-ray structure of complex of 3 shows typical length for single bonds between Cu–N 1 , Cu–N 2 , Cu–P 1 , and Cu–P 2

Synthesis of Silver(I) Complex ► PNP was treated with AgOTf in CH 2 Cl 2 which resulted in the formation of OTf ligand and the isolation of Complex 4 . ► Results were conformed By NMR and IR.
