Di-μ-iodo-bis [dicarbonyl(di-tert-butylphosphin)ruthenium(I)] (Ru-Ru) und Bis(tri-tert-butylphosphonium)-di-μ-iodo-bis[carbonyl-diiodo- (di-tert-butylphosphin)ruthenium(II)]

[(t-C4H9)3PH]2[{Ru(μI)I2(CO)[P(t-C4H9)2H]}2] is prepared by the reaction of RUC13 · (H2O)x with CO, NaI, and P(t-C4H9)3 in 2-methoxyethanol. Its IR, Raman, and NMR spectra are reported and discussed. [Ru(μ-I)(CO)2P(t-C4H9)2H)2 is obtained by the reaction of [Ru(μ-I)I(CO)3]2 with P(t-C4H9)3 in 2-methoxyethanol. The X18MAA′M′X′18 spin system of its 1H NMR spectrum is analysed.
