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)], (CeF5)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.
