N2 - In the presence of air, the interaction of AgSO3CF3 with phosphorus-nitrogen π-electron-rich compounds ArC(NPPh 2)[N(SiMe3)2] (Ar = phenyl, p-tolyl, 4-pyridyl, 3-pyridyl and 2-pyridyl) and 1,4-C6H4 {C(NPPh 2)[N(SiMe3)2]}2 in acetonitrile led to the formation of metallic silver and the oxidative cleavage product {[ArC(NH2)2](Ph2PO2)}n (Ar = phenyl, 1; p-tolyl, 2; 4-pyridyl, 3; 3-pyridyl, 4; 2-pyridyl, 5) and [{1,4-C6H4[C(NH2)2] 2}(Ph2PO2)2]n (6), respectively. Structural analyses of compounds 1-6 revealed that these ionic salts are held together by charge-assisted hydrogen bonds forming 1D, 2D and 3D polymeric networks.
