The synthesis and spectroscopic (IR, far-IR, H-1 and P-31 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)(2)Ag(pz(2)Bpz(2))]. Although the silver atom is essentially four-coordinate P2AgN2, Ag-P 2.4154(4) A, 2.5123(4) A, Ag-N 2.315(1) A, 2.357(1) A at ca. 150 K, NMR spectroscopy clearly distinguishes between the bonding character of the two different phosphorus atoms.
