Abstract

Red-brown [TiI4{o-C6H4(PMe2)(2)}] and [TiI4{o-C6H4(AsMe2)(2)}] have been prepared from the ligands and TiI4 in a 1:1 molar ratio in anhydrous CH2Cl2. They have been characterised by analysis, IR, H-1 and P-31{H-1} NMR and UV-Visible spectroscopy as appropriate and have six-coordinate (cis) octahedral geometries. Investigation of the yellow or fawn products from reactions of TiI4 and the ligands in a 1:2 molar ratio, and suggested in the literature to be bis(ligand)-Ti(IV) complexes, have shown that these are mixtures containing iodinated and oxidised ligands, but do not contain Ti(IV)-iodide complexes. The crystal structures of two iron-diarsine complexes [FeI2{o-C6H4(AsMe2)(2)}(2)] and [FeI2{o-C6H4(AsMe2)(2)}(2)]I-3 . 2CH(2)Cl(2) arising from iron iodide impurities in one commercial sample of TiI4 are reported. The complexes constitute a redox pair and the iron(III) complex is the first pseudo-octahedral iron(III) iodide complex to be structurally characterised.
