Abstract
The crystal structures of mononuclear (azido)(pentamethylcyclopentadienyl)iridium(III) complexes bearing 2- or 8-quinolinethiolate (n-Sqn-), [Cp*Ir(N3)(n-Sqn)] {n = 2 (1) or 8 (2); Cp* = η5-C5Me5} have been determined by X-ray analysis. The 2-Sqn complex, 1, acquires severe steric strains in the four-membered κ2N,S chelate ring, while the 8-Sqn isomer, 2, forms a strain-free five-membered planar κ2N,S chelate ring. It has also been revealed that the corresponding benzimidazole-2-thiolate (Hbimt-) complex, which was obtained similarly to the above n-Sqn complexes from [Cp*Ir(N3)2]2 and Na(Hbimt), takes an unsymmetrical dinuclear structure bridged by two Hbimt- ligands with different bonding modes, [Cp*Ir(N3){μ(S:N1)-Hbimt}{μ(S:S)-Hbimt}Ir(N3)Cp*] · MeOH (3).
