Reactions of [Ru(η5-C5H5)CIL2](L = PPh3, AsPh3, or SbPh3; L2= Ph2PCH2CH2PPh2 or Ph2PCH2PPh2) with 1,4-piperazinedicarbonitrile or 1-piperidinecarbonitrile in the presence of an anion (BF4–, PF6–, BPh4–, or ClO4–)

Abstract

Reactions of [Ru(η⁵-C₅H₅)CIL₂](L = PPh_3′ AsPh_3′ or SbPh_3′ L₂= Ph₂PCH₂CH₂PPh₂ or Ph₂PCH₂PPh₂) have been carried out with 1-piperidinecarbonitrile or 1,4-piperazinedicarbonitrile in the presence of a suitable anion (PF₆^–, BF₄^–, BPh₄^– or ClO₄^–). The products were found to be cationic mono-and bi-nuclear complexes which have been characterised by elemental analyses and spectroscopic (i.r., u.v.–visible, and n.m.r.) studies. Conductivity measurements have also been carried out to confirm the charges on these cationic species.
