trans-[RhCl(CO(PPh3)2[ in toluene. This same reaction in dichloromethane however yields the cis isomer 10b. When a larger excess of PPh3 is used, a mixture of compounds 11a and 11b is formed. An X-ray crystal structure study shows trans[Rh(SC6F5)(CO)(PPh3)2[ to exit as two polymorphs. 11a crystallises in the space group P21/n of the monoclinic system with a = 12.489(1), b = 15.430(5), c = 19.719(1) Å, α = γ
