Abstract

Crystallization of silver trifluoroacetate from chloroform solutions containing triphenylphosphine sulfide affords a trigonal and a monoclinic form of a 6:4 complex {[CF₃C(O)OAg]₆(Ph₃PS) ₄} of C₂ symmetry with different amounts of chloroform in the crystals. With the Ph₃PS components as template molecules, the CF₃C(O)OAg units are assembled to form a 6-membered metallacycle codetermined by metallophilic bonding and enclosed by a 24-membered ring [AgOCO]₆. A complex of the type [LAgOC(O)CF₃]₂, with L representing the isocyanide ligand ^pTolSO₂-CH ₂NC, has been shown to have a conventional bicyclic structure with three-coordinate silver atoms engaged in transannular metallophilic interactions.
