Abstract
In acetonitrile [{Ru(η-C6H6)Cl2}2] reacted with pyrazole (Hpz), 3,5-dimethylpyrazole (Me2Hpz), or with K[HB(Me2pz)3] to give products assigned as the amidine complexes [Ru(η-C6H6){NHCMe(R2pz)}(R2Hpz)]2+(R = H or Me). In methanol, reactions with pyrazoles afforded [Ru(η-C6H6)Cl(R2Hpz)2]+(R = H or Me), but in benzene only [Ru(η-C6H6)Cl2(Me2Hpz)] was formed. The complexes were characterised on the basis of spectroscopic studies.Keywords
