Abstract
We have investigated the reaction of dirhodium tetraacetate with the phosphine P( o-CH 3OH 6H 4)Ph 2 (P) under different experimental conditions. From these reactions we have been able to isolate the dirhodium tetraacetate phosphine mono-adduct. The crystal structure shows that in the solid state this compound forms a centrosymmetric dimer of the dimer, {Rh 2(O 2CCH 3) 4·P(0-CH 3OC 6H 4)Ph 2} 2, in which we oxygen atom from one acetate group in one Rh 2(O 2CCH 3) 4·P unit is axially coordinating one Rh atom on another Rh 2(O 2CCH 3) 4· P unit (Rh⋯) 2.347(3) Å intermolecular versus Rh⋯O 2.455(3) Å intermolecular), and vice versa. The RhRh bond distance is 2.414(1) Å while the intermolecular Rh⋯Rh distance is 3.45592) Å.
