General formation of trigonal-prismatic [Ag6X5(dppf)3]+ (X = Cl, Br, I) through an unusual ligand migration from NiX2(dppf) to AgOTf

Abstract

Use of NiX2(dppf) (X = Cl, Br, I) as a ligand transfer reagent to AgOTf results in the trigonal prismatic [Ag6X5(dppf)3]OTf complexes. Similar reactions with the dppe analogues give at least 4 different types of dppe-bridged coordinationpolymers.
