Abstract

The complexes C6F5InCl2, L [L = N, N, N’, N’-tetramethylethylenediamine (tmed), 2,2'-bipyridyl (bpy), 1,10-phenanthroline (phen), 2,2':6',2'- terpyridyl (tpy) or (Ph2PCH2)2] have been prepared by reaction of C6F5InCl2, diox (diox = 1,4-dioxan) with the appropriate ligands, and are considered to contain five-coordinate indium on the basis of indium- chlorine stretching frequencies. Monomeric structures are likely for all complexes except C6F5InCl2, tmed, which is dimeric with bridging tmed. Atmospheric moisture converts C6F5InCl2, L (L = phen or tpy) into monohydrates, in which water is not coordinated. Reaction of C6F5InCl2, diox with pyridine, triphenylphosphine and dimethyl sulphoxide causes quantitative rearrangement into the corresponding indium trichloride and tris-pentafluorophenylindium complexes. The derivatives (C6F5)nIn(ox)3-n(n = 1 or 2; ox = quinolin-8-olate) have been prepared by cleavage of (C6F5)3In, diox with quinolin-8-ol, and C6F5In(ox)2 has also been obtained from C6F5InCl2, diox and thallous quinolin-8-olate.
