S1. Comment

The reaction of Re₂(µ-PR₂)₂(CO)₈ with nucleophilic lithium organyls LiR' leads to the salts Li(Re₂(µ-PR₂)₂(CO)₇{ax-C(R')O} which then can be converted to Fischer-type carbene complexes (Haupt et al., 1998a). The title compound, (I), with R = ethyl and E, R' = phenyl, is an axial monocarbene complex with a Re₂P₂ ring and slightly distorted octahedral coordination at both Re atoms. The C(Ph)OEt carbene group with a Z configuration is axially attached to Re2 with a Re═C double-bond length of 2.098 (7) Å. The orientation of the ReCOEt group is parallel to the Re···Re vector with a Re···Re—C8—O8 torsion angle of -3.2 (6)°. The Re1—P bonds of 2.5154 (17) and 2.5122 (19) Å for P1 and P2, respectively, are slightly longer than those for Re2–P of 2.5024 (18) and 2.5023 (17) Å, and reflect the unsymmetrical monosubstitution of this compound. These distances are, on average, slightly shorter than the Re—P bonds of the related mono- and dicarbene complexes which have µ-PPh₂-bridging ligands instead (Haupt et al., 1998b). The average values for the enclosed ring angles are Re—P—Re = 104.35 (6)° and P–Re–P = 75.43 (6)°. The Re₂P₂ ring is folded, with an ReP₂/P₂Re dihedral angle of 6.2 (1)°. This is a well known effect due to an intramolecular balance of unsymmetrical or sterically unfavourable substituted carbonyl complexes of this type (Haupt et al., 1998a,b; Flörke & Petters, 2001). The C—Re—Re—C torsion angles range from 0.2 (4) to 8.8 (4)° (absolute values), in accordance with the ecliptic carbonyl-ligand arrangements.

S2. Experimental

The title compound was obtained by reaction of Li(Re₂(µ-PEt₂)₂(CO)₇{C(Ph)O)} with OEt₃BF₄ in CHCl₃ solution at room temperature. The synthesis of the precursor Li salt has been described earlier (Haupt et al., 1998a).

S3. Refinement

H atoms were placed at calculated positions, riding on the attached C atoms, with isotropic displacement parameters U_iso(H) = 1.2U_eq(C) [1.5U_eq(C) for methyl groups].

Special details

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.
