(Acetonitrile-κN)[2-(diphenylphosphan-yl)ethanamine-κN,P][(1,2,3,4,5-η)-1,2,3,4,5-pentamethylcyclopentadienyl]iron(II) hexafluoridophosphate tetrahydrofuran monosolvate.

In the title cationic Cp(*)Fe(II) complex, [Fe(C(10)H(15))(CH(3)CN)(C(14)H(16)NP)]PF(6)·C(4)H(8)O, the metal ion is coordinated by the η(5)-Cp* ring as well as the P and N atoms of the chelating 2-(diphenyl-phosphino)ethyl-amine ligand and an additional acetonitrile mol-ecule in a piano-chair conformation. The PF(6) (-) anion is disordered over two sets of sites with occupancies of 0.779 (7) and 0.221 (7).
