| Abstract: | 4-Tetrafluoropyridyl silver(I), AgC5F4N, has been obtained from Me3SiC5F4N and AgF in nearly quantitative yield. Reactions with bis(triphenylphosphoranyliden)ammonium chloride, [PNP]Cl, gave crystalline material of the composition [PNP][Ag(C5F4N)2]. Redox transmetallations of AgC5F4N and group 12-14 elements Zn, Cd, Hg, Ga, In, Sn yielded the corresponding 4-tetrafluoropyridyl element compounds. The molecular structures of [PNP][Ag(C5F4N)2], Hg(C5F4N)2, Ga(C5F4N)3 · EtCN · H2O, In(C5F4N)3 · 2EtCN and Sn(C5F4N)4 are discussed. |
