Djr. Brook et al., DISPROPORTIONATION OF DIIRON NONACARBONYL IN TNF SOLUTION - FORMATIONAND STRUCTURE OF FE(THF)(4)[HFE3(CO)(11)](2), Inorganic chemistry, 34(22), 1995, pp. 5691
Tetrakis(tetrahydrofuran)iron(II) -carbonyl)decacarbony(mu-hydrido)tri
ferrate-(1-)), Fe(THF)(4)[HFe3(CO)(11)](2) (1), was isolated as a mino
r product of the reaction of diron nonacarbonyl and tetrahydrofuran in
benzene under vacuum. Compound 1 is the first example of a transition
metal complex of the HFe3(CO)(11)(-) anion and was characterized by X
-ray crystallography and infrared spectroscopy. Contrary to previous r
eports, the reaction between Fe-2(CO)(9) and THF does not appear to pr
oduce the HFe3(CO)(11)(-) anion as the major product.
