  The square-planar complex [Ir(C7H4NS2)(CO)(PPh(3))(2)] (1) is obtained in high yield from the reaction of lithium benzothiazole-2-thiolate (LiC7H4NS2) with Vaska's complex, [IrCl(CO)(PPh(3))(2)]. Coordination of the new ligand in 1 and in the homologous rhodium complex should occur through the sulfur atom, as shown by their protonation reactions with HBF4, which give the hydridoiridium(III) complex [IrH(C7H4NS2)(CO)(PPh(3))(2)]BF4 and the rhodium(I) compound [Rh(CO)(PPh(3))(2)(C7H5NS2)]BF4, respectively. The neutral ligand C7H5NS2 reacts with 1 to give [IrH(C7H4NS2)(2)(CO)(PPh(3))(2)] (4). Complex 1 adds dihydrogen, methyl iodide, and dioxygen. The dioxygen complex [Ir(C7H4NS2)(O-2)(CO)(PPh(3))(2)] (7) undergoes an intramolecular oxidation of the carbonyl ligand, catalyzed by water, to yield the carbonate complex [Ir(C7H4NS2)(CO3)(PPh(3))(2)] (8). Labeling studies show that the reaction is multistep and oxygen from water is incorporated into the carbonate ligand. Sulfur dioxide is oxidized by complex 7, but in addition, activation of the carbonyl group occurs by attack of the heterocyclic nitrogen of the benzothiazole-2-thiolate ligand to give [IrC(O)NC(S)SC6H4}(SO4)(PPh(3))(2)] (11). In 8 both benzothiazole-2-thiolate and carbonate anions act as N,S- and O,O-chelating ligands. The structure of II shows a C,S-chelating ligand, obtained by an unprecedented incorporation of the carbonyl group of 7 into the benzothiazole-2-thiolate through the heterocyclic nitrogen, in addition to a chelating sulfate ligand.
• Chemical evidence of polynuclear intermediates in a ligand redistribution equilibrium between dinuclear rhodium complexes. X-ray structure of [Rh2(μ-bzta)2(CO)3(PPh3)] (bzta = benzothiazole-2-thiolate)

  The monosubstituted dinuclear complex [Rh2(mu-bzta)2(CO)3(PPh3)] (3) has been isolated from the reaction of the tetracarbonyl complex [Rh(mu-bzta)(CO)2)2] (1) with triphenylphosphine. The crystal structural analysis of 3 has confirmed this complex to be dinuclear. The two metal centres exhibit distorted square-planar coordination and are bridged by two bzta ligands in a cis,cis and head-to-tail arrangement. The added PPh3 group has been located trans to a S atom of the bridging ligand. In solution, complex 3 is in dynamic equilibrium with 1 and the disubstituted complex [Rh(mu-bzta)(CO)(PPh3)}2] (2) as a result of a reorganization process. Scrambling experiments carried out with related 6-methylbenzothiazole-2-thiolate complexes suggest that polynuclear intermediates are responsible for the ligand-redistribution equilibrium. Addition of further triphenylphosphine to the equilibrium mixture gives 2 quantitatively. Complex 2 reacts with triphenylphosphine to give the mononuclear complex trans-[Rh(bzta)(CO)(PPh3)2] (8) in high yield, as a result of a bridge-splitting reaction.
