Abstract: The title compound, [RhBr(C₁₈H₁₅P)₂(CO)], can be characterized as a rhodium(I) Vaska-type compound based only on the spectroscopic [_KBr(CO), ³¹P] data. A low-temperature X-ray crystallographic analysis shows that the compound possesses a crystallographically imposed centre of symmetry with a statistically disordered Br atom and CO group. The essentially different occupancies for the Br atom and the CO group [0.283 (2) and 0.717 (2), respectively] suggest that the compound exists as a mixture of rhodium(0), rhodium(I) and rhodium(II) complexes.
