| Abstract: | A series of M(CO)5I]− and M2(CO)10I]− anion complexes have been synthesized by the photochemical reaction of PhCH2N(CH3)3I or FcCH2N(CH3)3I (Fc=ferrocenyl) with M(CO)6 (M = Cr, Mo or W), and characterized by elemental analyses, i.r., 1H-n.m.r. and 13C-n.m.r. spectra in the case of the molybdenum and tungsten complexes. These complexes exhibit considerably different electrochemical behavior, when investigated by cyclic voltammetry. The crystal structures of PhCH2N(CH3)3]Cr(CO)5I] and FcCH2N(CH3)3]W2(CO)10I] have been determined by X-ray diffraction, indicating that only weak contacts maybe exist between anions and cations by the I...H bond in the former, and there are no direct interactions between anions and cations in the latter. |
