The structural definition of adducts of stoichiometry AgX:dppf (1:1)(n), X = simple anion, dppf = bis(diphenylphosphino)ferrocene

AgX:dppf (1:1)(n), X = simple (pseudo-)halide or oxy- anion, 'dppf' = bis(diphenyl phosphino)ferrocene, have been prepared. FWhn X = Cl, Br, I, SCN, OCN, CN, NO3, O2CCH3, n = 2, the form is dimeric [(dppf-P,P′)Ag(μ-X)2Ag(P,P′-dppf)]; for X = I, SCN the form is [Ag(μ-X)2(P-dppf-P′)2Ag′]; for X = O2CCF3, n = ∞, the form is an extended polymer: ⋯Ag(O · CO · CF3)(P-dppf-P′)Ag′(O⋯.
