Abstract: The title compound, [Rh₂(C₂₈H₄₀O₃P)₂(C₂H₃N)₂(CO)₂]·1.5CH₂Cl₂, contains a dimeric rhodacyclic complex, having inversion symmetry. The Rh atoms are joined by bridging phosphites and additionally each is coordinated by a CO and an acetonitrile. Half of the tert-butyl groups are rotationally disordered, but weak C-HO interactions prevent this from occurring in the other two groups.
