IRON DODECACARBONYL Chemical Properties,Uses,Production
Chemical Properties
stabilized with 5%–10% methanol; black crystal(s); sensitive to air [STR93]
Chemical Properties
Tri-iron dodecacarbonyl forms deep green, diamagnetic crystals which decompose at 140°C, but which can be sublimed slowly in vacuo. It dissolves in organic solvents and in pentacarbonyl iron in which its molecular weight corresponds to Fe3(CO)12.
Preparation
Tri-iron Dodecacarbonyl was first obtained by thermal decomposition of non aqueous solutions of the enneacarbonyl at 100°C : 6Fe2(CO)9 -> 2Fe3(CO)12+6Fe(CO)5 but is now usually prepared from solutions of carbonylferrate anions. One method uses the oxidation of these ions with manganese(IV) oxide followed by acidification and extraction of the carbonyl into petroleum ether. In another method,iron pentacarbonyl is treated with aqueous triethylamine to form the dark red [Et3NH][Fe3(CO)11H] which is then acidified and the carbonyl extracted into petroleum ether.
Structure and conformation
The structure of Fe3(CO)12 (Fig.9) is related to that of Fe2(CO)9 in that it can be
described as a triangular metal cluster in which one bridging group of the Fe2(CO)9 system is replaced by an Fe(CO)4 group. This X-ray data is in agreement with the M?ssbauer
spectrum which shows the presence of two types of iron atom ; two of the iron atoms
show substantial quadrupole splitting and have isomer shifts similar to those of the iron
atoms in Fe2(CO)9, while the other iron atom shows little splitting as might be expected for
an octahedral environment. A similar structure is possessed by the [Fe3(CO)11H] anion in
which one of the bridging carbonyl groups is replaced by a bridging hydrogen atom.
