Abstract
The monomeric complexes [Ag(PPh3)2]X (X = ClO4 − or NO3) was synthesized by a metathesis reaction of [Ag2(PPh3)4(μ-SO4)] with BaX2 (where X = ClO4 − or NO3 −) in ethanol. The reactivity of [Ag(PPh3)2]X (where X = ClO4 − or NO3 −) with some potential N-donor bridging ligands viz. 4,4′ bipyridine and pyrazine yielded dimeric complexes of the type [Ag2(PPh3)4(μ-L-L)]X2 (where L-L = 4,4′-bipyridine or pyrazine, and X = ClO4 − or NO3 −). All these complexes were characterized by infrared spectroscopy, conductivity measurements, cyclic voltammetry, 1H NMR, and electronic spectroscopy.
