(Received 6 November 2008; accepted 7 December 2008; online 13 December 2008)

The title compound, [Fe(C₈H₅)(C₂₂H₁₆P)(C₃H₉P)₃], was synthesized by the addition of phenylethine to a solution of the parent methyl iron complex Fe(CH₃){P(C₆H₅)₂(C₁₀H₆)}(PMe₃)₃ at 213 K, accompanied by evolution of methane. The coordination around the iron center can be described as slightly distorted octahedral [Fe—P 2.2485 (12)–2.2902 (12) Å; Fe—C 1.918 (5), 2.015 (4) Å], with a meridional arrangement of the trimethylphosphine ligands and the introduced terminal alkinyl-ligand trans to the P(Ph)₂-anchoring group.

Comment top

Recently, much attention has been paid to the use of highly active bis(imino) pyridine iron complexes for ethylene polymerization and alpha-olefine oligomerization as catalyst precursors reported by Britovsek et al. (1998) and Small et al. (1998). At this stage it is remarkable how little is known about this type of reactive intermediates. With labile methyl iron complexes in the presence P(Ph)₂-anchoring groups we were able to synthesize five-membered metallacyles under smooth conditions (see Beck et al. 2008). These complexes represents model compounds for the catalytic functionalization of C,C bonds. Related, phenylethinyl-iron(II) complexes were prepared by Venturi et al. (2004) and Costuas et al. (2004). The title compound Fe(CCPh){P(C₆H₅)₂(C₁₀H₆)}(PMe₃)₃ (1), was synthesized by addition of phenylethine to a solution of the parent methyl iron complex Fe(CH₃){P(C₆H₅)₂(C₁₀H₆)}(PMe₃)₃ at low temperature (213 K), accompanied by evolution of methane.

The meridional-cis arrangement of the ligands in the configuration remained stable when the reaction is finished, by means no rearrangement occurred because of different trans influence of the alkinyl carbon atom and no indication for isomers after the reaction was completed. From pentane solutions at 253 K orange-red crystal in form of needles were obtained, which were suitable for X-ray diffraction. The molecular structure of 1 is shown in Figure 1. The iron atom attains an octahedral coordination with a meridional arrangement of the trimethylphosphine ligands by two trans PMe₃ orientated groups (P3—Fe1—P2 = 158.97 (5)°) a cis disposed PMe₃ group (P4) trans to the metallated carbon (C1) atom (C1—Fe1—P4 = 174.38 (14)°), and the chelating phosphorus atom (P1) trans to the alkinyl group (CCPh) with an angle of (C11—Fe1—P1 = 173.69 (14)°). The inner bond angles of the trimethylphosphine ligands are close to 90°, with the smallest involving the bite angle of the five-membered chelate ring (C1—Fe1—P1 = 84.07 (13)°). The sum of internal angles is 537°, indicating considerable relaxation of the metallacycle towards planarity. The Fe—P bond lengths fall within the range observed for other Fe(II) complexes containing PMe₃ groups (Venturi et al., 2004). The complex contains two different Fe—C bonds with sp, and sp² hybridization with bond lengths of 1.918 (5) and 2.015 (4) Å, respectively, which are consistent with those in related Cp-stabilized iron(II) complexes with terminal alkinyl groups reported by Costuas et al. (2004).

Experimental top

Standard vacuum techniques were used in manipulations of volatile and air sensitive material. Literature methods were applied in the preparation of dimethyltetrakis(trimethylphosphine)iron(II) (Karsch, 1977), and 1-Diphenylphosphanyl-naphthaline (Carré et al., 2000). Other chemicals were used as purchased. The title compound was synthesized by combining a solution of phenylethine (140 mg, 1.37 mmol) in 50 ml of THF at -70 °C with a sample of Fe(CH₃){P(C₆H₅)₂(C₁₀H₆)}(PMe₃)₃ (836 mg, 1.37 mmol) in 50 ml of THF, effecting a change of color from red to orange. After warm-up the mixture was kept stirring at 293 K for 16 h, and then the volatiles were removed in vacuo to give orange solid. This was dissolved in 50 ml of pentane and crystallized at 253 K to give yellow crystals, which were suitable for X-ray diffraction. Yield 391 mg (41%); 396–398 K (dec.).

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
