Tris(acetonitrile)cyclopentadienylruthenium hexafluorophosphate is an

cyclopentadienyl ligand (Cp) is bonded in an η5
manner to the Ru(II) center.

Preparation

The title complex is synthesized in two steps from the (benzene)ruthenium dichloride dimer. In the first step, the Cp− group is installed using cyclopentadienylthallium:[1]

[(C6H6)RuCl2]2 + 2 TlCp + 2 NH4PF6 → 2 [Cp(C6H6)Ru]PF6 + 2 TlCl + 2 NH4Cl

The second step entails photochemical displacement of the benzene ligand, which is replaced by three equivalents of acetonitrile (MeCN):

[Cp(C6H6)Ru]PF6 + 3 MeCN → [CpRu(NCMe)3]PF6 + C6H6
