摘要
Rhodium(I) carbonyl complexes, namely [Rh(CO)2ClL] where L = thiourea (Tu), 1,3-diphenyl-2-thiourea (DTu), dithizone (Dtz), indole (1d), 3-chloropyridine (Clpy), 3-hydroxypyridine (HOpy), 3-methylpyridine (Mepy), 2,5-dimethylpyridine (Me2py) or 2,5-dichloropyridine (Cl2py)] were prepared. [Rh(CO)2Cl(Clpy)2] has also been isolated. In the (Tu) complex, nu(C-S) occurs at ca. 710 cm-1, indicating the presence of a metal-sulphur bond. The carbonyl stretching frequencies in [Rh(CO)2ClL] and [Rh(CO)2ClL2] occur at ca. 2100-1990 and 1830-1800 cm-1, respectively. PPh3 reacts with the complexes to form trans-[Rh(CO)Cl(PPh3)2]. The complexes were characterized by elemental analyses, conductivity measurements and by their i.r. spectra.
