Organoindium compounds. II. Some coordination derivatives of trispentafluorophenylindium

Abstract

The complexes (C₆F₅In,L [L = pyridine (py), Ph₃P, Ph₃PO, Ph₃AsO, or N,N,N?,N'-tetramethylethylenediamine (tmed)], (C_eF₅)₃1n(OSMe₂)₂, and [(C₆F₅)₃)aIn]₂bipy (bipy = 2,2'-bipyridyl) have been prepared by reaction of (C₆F₅)₃In,diox (diox = 1,4-dioxan) with the appropriate ligands, and (C₆F₅)₃1n,AsPh₃,( C₆F₅)₃ (THF)₂ (THF = tetrahydrofuran), and (C₆F₅)₃1n]₂(Ph₂PCH₂)₂ have been similarly obtained from (C₆F₅)₃In,OEt₂. Monomeric structures with four-coordinate indium are proposed for the complexes (C₆F₅)₃In,L (L = py, Ph₃P, Ph₃As, Ph₃PO,or Ph₃AsO), and monomeric five-coordinate structures for the complexes (C₆F₅)₃1n(L)₂ (L = Me₂SO or THF). The derivatives [(C₆F₅)₃1n]₂L [L = bipy or (Ph₂PCH₂)₂] and (C₆F₅)₃In,tmed are considered to have bridging ligands with four- and five- coordinate indium respectively.
