N2 - Reactions of [(η6-arene)RuCl(μ-Cl)2] [arene = benzene or p-cymene (p-isopropyltoluene)] have been carried out with 4-cyano-pyridine (4-CNpy), o-aminophenol (oap), o-phenylenediamine (opda), p-phenylenediamine (ppda) and 2,6-dimethyl-5-oxo-3-thioxo-2,3,4,5-tetrahydro-1,2,4-triazine (taz). The isolated complexes are of the types [(η6-C6H6)RuCl2L] [L = 4-CNpy (Ia) or oap (IIa)], [(η6-C6H6)RuClL2]Cl [L = oap (IIIa); L2 (bidentate) = opda (IVa) or taz (VIa)] or [(η6C6H6)Cl2Ru2(μ-ppda)] (VIIIa). Complexes IVa and VIa undergo anion exchange with KPF6 to give the corresponding hexafluorophosphates (Va and VIIa). The p- cymene analogues (Ib-VIIIb) have been obtained. Conductance measurements, thermogravimetry and spectroscopic (IR and 1H and 13C NMR) methods have been used to study the new compounds. The structure of VIIb was determined by X-ray diffraction methods. The ruthenium atom of the cation of VIIB is coordinated by the 4-amino (RuN = 2.140(2) Å) and 3-thioxo (RuS = 2.354(1) Å) groups of the triazine and a chloride ligand (RuCl = 2.394(1) Å). The η6-p-cymene ring completes the hexacoordination. © 1994.
