Description
IRON DODECACARBONYL, also known as Tri-iron dodecacarbonyl, is a chemical compound with the formula Fe3(CO)12. It is a black crystalline substance that is sensitive to air and can be stabilized with 5%–10% methanol. The compound forms deep green, diamagnetic crystals which decompose at 140°C and can be sublimed slowly in vacuo. It is soluble in organic solvents and in pentacarbonyl iron, where 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.
Check Digit Verification of cas no
The CAS Registry Mumber 12088-65-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,8 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 12088-65:
(7*1)+(6*2)+(5*0)+(4*8)+(3*8)+(2*6)+(1*5)=92
92 % 10 = 2
So 12088-65-2 is a valid CAS Registry Number.
