The synthesis and characterisation of new mono- and dinuclear p-cymene-ruthenium(II) complexes (p-cymene = MeC6H4Pri-p) containing 3-substituted pyrazoles (LH) or pyrazolates (L) as ligands are reported .The new complexes belong to one of the following families (not all possible combinations): 6-p-cymene)RuCl2(LH)> (1-5),6-p-cymene)RuCl(LH)2>BF4 (6-11), 6-p-cymene)RuL(acac)> (acac = acetylacetonate) (12-15), 6-p-cymene)Ru(acac)(LH)>BF4 (16-19), 6-p-cymene)Ru(LH)3>2 (20-22), 6-p-cymene)RuL(LH)2>BF4 (23-25), 6-p-cymene)RuL2(LH)> (26-28), and the dinuclear 6-p-cymene)RuCl(μ-L)2M(CO)2> (M = Rh, Ir) (29-34).For the ruthenium-iridium complexes 6-p-cymene)RuCl(μ-ClPhpz)2Ir(CO)2> (33) and 6-p-cymene)RuCl(μ-MePhpz)2Ir(CO)2> (34) an equilibrium in solution is reached between two isomers that implies a reversible metal-metal bond formation accompanied by halide migration.
