metal-organic compounds
The title compound, [2(1,2,3,3a,6a-η)-1,4-dihydropentalenyl][μ-(1,2,3,3a,6a-η : 3a,4,5,6,6a-η)pentalene][1(η5)-pentamethylcyclopentadien]diiron, [Fe2(C8H7)(C10H15)(C8H6)], has a metallocenic structure with the two pentalene ligands adopting an eclipsed conformation. In the central pentalene ligand, all the peripheral bonds are of similar length whereas the bridge bond is longer; there are two significantly different Fe—C distances, i.e. a mean value of 2.121 (3) Å for the Fe—Cbridge distances and a mean value of 2.028 (3) Å for the distances from the Fe atoms to all other C atoms. In the terminal pentalene ligand, the C—C and C—Fe distances in the ring bonded to the Fe atom are all similar.
