Abstract

A series of new rhenium(iii) complexes, [ReL2]+, where LH = a 2-formylpyridine thiosemicarbazone have been synthesised and characterised. The complexes have been synthesised from the Re(v) starting material [ReOCl3(PPh3)2] and from [ReO4]− in the presence of triphenylphosphine. All of the new compounds have been characterised by X-ray crystallography, NMR and mass spectroscopy. In all cases the Re atom is in a distorted octahedral environment with two tridentate deprotonated thiosemicarbazones binding as monoanionic ligands through the sulfur, pyridyl nitrogen and azamethinic nitrogen in a mer (azomethine nitrogen atoms trans) configuration. Electrochemical measurements show that the complex..
