The reaction of [ReOCl3(PPh3)(2)] with N-(2-hydroxybenzyl)-2-mercaptoaniline (H(3)hbma) (2) and 2-mercaptopyridine in hot CHCl3 yields [ReO(eta(2)-HOC6H4-2-CH2NC6H4S)(eta(2)-SC5H4N) (3). The structure of 3 consists of distorted octahedral Re(V) monomers. The coordination geometry at the rhenium is defined by a terminal ore-group, the nitrogen and sulfur donors of the chelating mercaptopyridine, the nitrogen and sulfur donors of a bidentate (Hhbma)(2-) ligand, and the phosphorus of the PPh3 group. The -C6H4OH arm of (Hhbma)(2-) is pendant, and the coordinated nitrogen of this ligand is present as a deprotonated amido nitrogen. (C) 2000 Elsevier Science S.A. All rights reserved.
