Versatile Coordination of Ag^I and Cu^I Ions towards cyclo-As₅ Ligands.

ABSTRACT: The reactions of the cyclo-As₅ complex [Cp*Fe(η⁵ -As₅ )] (B) with the Ag^I and Cu^I salts of the weakly coordinating anion (WCA) [FAl{OC₆ F₁₀ (C₆ F₅ )}₃ ]^- ([FAl]^- ) are studied. These reactions allow the synthesis of the mononuclear complexes [M(η⁵  : η² -B)₂ ][FAl] (M=Ag (1), Cu (2)) when a ratio of B/M(FAl) 2 : 1 is used. Compound 1 shows an unusual disorder of the central Ag^I cation between two π-coordinating cyclo-As₅ ligands, which is absent in 2 pointing to a weak interaction of the Ag center towards the cyclo-As₅ ligands in B. When the ratio of B/Ag(FAl) is changed to 3 : 1 or 1 : 1, the r
