| Abstract: | The synthesis and spectroscopic (IR, far-IR, 1H and 31P NMR) characterization of the new complex Ag(pzTp)(PPh3)2 is reported, with a single crystal X-ray structure determination showing it to assume the form [(Ph3P)2Ag(pz2Bpz2)]. Although the silver atom is essentially four-coordinate P2AgN2, Ag–P 2.4154(4) Å, 2.5123(4) Å, Ag–N 2.315(1) Å, 2.357(1) Å at ca. 150 K, NMR spectroscopy clearly distinguishes between the bonding character of the two different phosphorus atoms. |
