Abstract: The Ru atoms of the title compound, [Ru₂Br₂(C₄H₄N₂)(C₅H₅N)₈](PF₆)₂.2C₃H₇NO, are coordinated by the four N atoms of the pyridine (py) ligands and a bromide. Two such units are bridged by a pyrazine (pz) unit, which is disposed about a centre of inversion, so as to form a trans pseudo-octahedral geometry about Ru. The py units are in an eclipsed conformation when viewed down the internuclear axis. The Ru-N(pz) distance is 2.079 (3) Å, while the Ru-Br distance is 2.5524 (4) Å.
