Abstract

Treatment of hydrated ruthenium(III) chloride with tetra-2-pyridyl-1,4-pyrazine (tppz) in refluxing ethoxyethanol afforded the homoleptic dinuclear complex [(tppz) Ru(mu-tppz) Ru(tppz)](4+) (1) besides small amounts of the species [ Ru(tppz)(2)](2+). The title complex 1 was obtained as purple crystals and characterized as its hexafluoridophosphate salt by NMR spectroscopy, mass spectrometry and microanalyses. The molecular structure of 1(PF6)(4) has been established by X-ray crystallography.
