摘要:
                                The products of the reactions of [Re(CO)(5)Cl] with 1-(benzothiazol-2-ylidene)-3-methylthiourea (Hmbt) and bis {1,2-(benzothiazol-2-ylidene)}thiourea (Hdbt) were studied. The X-ray crystal structure of (mu-mbt)(2)[Re(CO)(3)](2) shows that bridging between the two metal centres occurs via the two thiolic sulfur atoms of the two mbt ligands. One mbt ligand is also coordinated via a benzothiazole nitrogen atom to a rhenium(I) atom, with the second mbt ligand attached to the metal via a thiourea imino nitrogen. In the complex (mu-dbt)(2)[Re(CO)(3)](2). each dbt ligand bridges two metal centres in a '2 + 1' manner, with each rhenium atom in a N2SC3 donor atom set. (C) 2012 Elsevier B.V. All rights reserved.
