 Abstract    von Ph3P=C=PPh3 mit Fe(CO)5; Molekülstrukturen von (CO)4Fe=C=C=PPh3 und Fe3(CO)9(/X3-r72-C=C-PPh3) Reaction o f Ph3P= C =P Ph3 w ith Fe(C O)5; M olecular Structures of (CO)4F e= C =C = P P h3 and Fe3(C O)9(/i3-/72-C = C -P P h 3). W olfgang P e tz * a, Frank W eller5 aGmelin- The ylide Ph3P=C=PPh3 reacts with Fe(CO)5 in toluene to give the metallacumulene (CO)4Fe=C=C=PPh3 (1) and 0=PPh3. A mixture of the ylide with its hydrolysis product Ph2P(0)-CH=PPh3 produces the trinuclear cluster Fe3(CO)9(^ 3-?/2-C=CPPh3) (2) in low yields which can also be obtained from 1 and Fe2(CO)9. Both compounds contain the same ligand bonded in a terminal (1) and in a bridging (2) manner. 1 and 2 crystallize in the monoclinic space groups P2(l)/n and P2(l)/c, respectively, with the unit cell parameters a = 1008.35(10), b= 1167.89(10), c = 1875.10(10) pm, ß = 99.824(10)° for 1 and a = 853.6(2), b = 1966.6(4), c = 1770.2(4) pm; ß = 99.05(3)° for 2. The compounds are further characterized by IR and NMR (l3C , 31P) spectroscopy and elemental analyses.
