✦ Synopsis

Rhodium(I) carbonyl complexes, namely [Rh(CO)2C1L ]

where L = thiourea (Tu), 1,3-diphenyl-2-thiourea (DTu), dithizone (Dtz), indole (Id), 3-chloropyridine (Clpy), 3hydroxypyridine (HOpy), 3-methylpyridine (Mepy), 2,5dimethylpyridine (Me2py) or 2,5-dichloropyridine (C12py)] were prepared. [Rh(CO)2CI(Clpy)2 ] has also been isolated. In the (Tu) complex, v(C--S) occurs at ca. 710cm -1 indicating the presence of a metal-sulphur bond. The carbonyl stretching frequencies in [Rh(CO)2C1L] and [Rh(CO)2C1L2] 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.
