Tetramesityldiiron is an
organoiron compound with the formula Fe2(C6H2(CH3)3)4. It is a red, air-sensitive solid that is used as a precursor to other iron complexes. It adopts a
centrosymmetric structure.[1] The complex is a
Lewis acid, forming monomeric
adducts, e.g. Fe(C6H2(CH3)3)2pyridine2. The complex is prepared by treating ferrous halides with the
Grignard reagent formed from
mesityl bromide:[2][3]
