The first example of a bromo- and phosphido-bridged binuclear rhenium carbonyl complex

The ionic crystals of the title complex, tetra­phenyl­phos­pho­nium μ-bromo-bromo­hepta­carbonyl-μ-di­cyclo­hexyl­phos­phido-dirhenate, (C₂₄H₂₀P)[Re₂Br₂(C₁₂H₂₂P)(CO)₇], are built of tetra­phenyl­phospho­nium cations and (μ-Br)(μ-PCy₂)(CO)₇BrRe₂⁻ anions. The latter is the first example of a bromo- and phosphido-bridged binuclear rhenium carbonyl complex. The Re—Br bond lengths are 2.6786 (7) and 2.6482 (7) Å for the bridging Br atom, and 2.6146 (8) Å for the terminal Br ligand. The Re...Re distance of 3.930 Å is clearly non-bonding which is not unexpected for the 36 valence-electron complex anion.

General Notes



ABSTM_02  When printed, the submitted absorption T values will be replaced
          by the scaled T values. Since the ratio of scaled T's is
          identical to the ratio of reported T values, the scaling does
          not imply a change to the absorption corrections used in the
          study.
          Ratio of Tmax expected/reported      0.334
          Tmax scaled      0.333 Tmin scaled      0.129

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 on F² for ALL reflections except for 0 with very negative F²

or flagged by the user for potential systematic errors. Weighted R-factors

wR and all goodnesses of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The observed criterion of F² > σ(F²) is used only for calculating _R_factor_obs 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.
