calf-thymus (CT) DNA by a series of thioether metal complexes. The complexes of interest are rhodium and iridium complexes containing thiacrown ligands 1,4,7-trithiacyclononane (9S3) and 1-oxa-4,7-dithiacyclononane (9S2O), and the complexes are abbreviated as [Rh(9S3)Cl3], [Rh(9S2O)Cl3], and [Ir(9S3)Cl3]. In the nicking assay, pBR322 was treated with each complex and irradiated at 254 and 350 nm, respectively

Reaction of MI species with [9]aneS3 affords half-sandwich complexes including [M([9]aneS3)(cod)]+, [M([9]aneS3)(coe)2]+(M = Rh, Ir; coe = cyclooctene), [(Rh([9]aneS3)(C2H4)2]+, [Rh([9]aneS3)(C2H4)(PR3)]+(R = Ph, cyclohexyl), [Rh([9]aneS3)(CO)(PPh3)]+ and [Rh([9]aneS3)(tcne)(NCMe)]+; crystal structure determinations of [M([9]aneS3)(cod)]+(M = Rh, Ir) and [Rh([9]aneS3)(C2H4)2]+ confirm these complexes to be five-coordinate, and the latter species reacts with C–X (X = halide) bonds.

The reactions of RhCl3 . 3H(2)O and PtCl4 with 1,4,7-trithiacyclononane in ethanol lead to the formation of (S-3-ethano-9)RhCl3 and (S-3-ethano-9)PtCl4, respectively. The complexes catalyzed polymerization of ethylene in pentane in the presence of methylalumoxane (MAO) at 70 degrees C and at ethylene pressure of 10 bar. The obtained polyethylenes had an averaged molecular weight of M(w) = 272,000 ((S-3-ethano-9)RhCl3) and 901,000 ((S-3-ethano-9)PtCl4) and narrow molecular weight distributions of M(w)/M(n) = 2.95 (M(n) = 92,000) ((S-3-ethano-9)RhCl3) and M(w)/M(n) = 4.0 (M(n) = 226,000) ((S-3-ethano-9)PtCl4). On the basis of the narrow molecular weight distribution the catalysts can be considered as single-site catalysts.

β= 96.844(18)° and Z= 8. The structure shows a quasi-square-pyramidal complex cation. Treatment of [Rh2(CO)4Cl2] with [9]aneS3 and NH4PF6 yielded the dimeric complex [Rh2([9]aneS3)2(µ-CO)3][PF6]2. Reaction of [Rh([9]aneS3)(C2H4)L]+[L = C2H4 or P(C6H11)3] with halogenated substrates afforded insoluble [Rh([9]aneS3)X3](X = Cl or I), while no reaction was observed with C6H6 or SiEt3H.
