Abstract Reaction of [Rh(CO)2Cl]2 with Bu t SLi followed by refluxing with PPh3 yields [Rh(μ-SBu t )(CO)(PPh3)]2(1). The structure of (1) has been determined by X-ray crystallography. Empirical formula: Rh2P2S2C46H48O2,M=964.78, triclinic, P¯1,a=11.408(9),b=13.241(8),c=15.830(3) Å,α=93.67(3),β=93.12(5),γ=110.8(6)°,Z=2,D calc=1.44 g cm−3,R=0.048 (R w =0.062) for 5939 observed reflections. In the solid state, the compound exhibitscis geometry with respect to the phosphine and CO ligands. The geometry about the two metals is essentially square planar, with a dihedral angle of 103.2°, and a “butterfly angle” of 102.3°. Compound (1) is stereochemically rigid on the NMR time scale from −80 to +80°C.
