Ru(II)-p-cymene complexes (1–3) containing picolyl based pseudo-acylthiourea ligands (L1-L3) were synthesized and characterized. The crystallographic study confirmed the molecular structures of all the ligands (L1-L3) and complex 3. The catalytic activity of the complexes was tested mainly towards TH of carbonyl compounds and nitroarenes. The influence of steric and electronic effects of the ligands

(NBu4)[ReOCl4] reacts with N-picolyi-N'-benzoylthiourea (H(2)Picbtu) in acetone under formation of the deep-green oxorhenium(V) complex (NBu4)(2)[Re2O2Cl5(Hpicbtu)}(2)O], which was studied by X-ray diffraction. Two dimeric units with each one bridging, singly deprotonated thiourea ligand are connected by an oxo ligand. Inside the subunits, Hpicbtu(-) coordinates as S,O chelate with a six-membered chelate ring to one rhenium atom, while a five-membered chelate ring is established with the second Re atom and the nitrogen atoms of the picolylamine building block. The compound represents one of the very rare examples of anionic mu-oxorhenium(V) complexes. (c) 2008 Elsevier B.V. All rights reserved.
