Abstract

The reaction of ReOCl3(PPh3)2 with the potentially tridentate ligand S-benzyl-3-[(2-hydroxyphenyl)methylene]dithiocarbazate ([ONS] donor set) and para-substituted benzenethiols [C6H4X-4-SH] (where X = H, F, Cl, Br and OCH3) in the presence of Et3N afforded a series of integrated '3 + 1' oxorhenium(V) complexes with general formula [ReO{η3-OC6H4-2-CH=N-N=C(SCH2Ph)-S}(η1-C6H4X-4-S)]. The molecular structure of [ReO{η3-OC6H4-2-CH=N-N=C(SCH2Ph)-S}(η1-C6H4F-4-S)] (4) was determined by single-crystal X-ray analysis. Complex 4 consists of a central oxorhenium(V) core with phenolic oxygen, azomethine nitrogen and thiol sulfur donor from the thiosemicarbazone Schiff base ligand and one sulfur donor from monothiol ligand completing a distorted square pyramidal environment. Crystal data for 4, C21H16FN2O2S3Re: orthorhombic, P212121, a = 5.6682(3), b = 11.6600(6), c = 31.697(2) Å, V = 2094.9(2) Å3, Z = 4. (C) 2000 Elsevier Science S.A.
