The title complex, [RuBr₂(C₅H₅N)₄], contains two independent complex molecules in each of which the Ru^II atom is located on a site of 222 symmetry and has a distorted octahedral coordination geometry with four pyridine N atoms and two Br atoms. The Br aroms are trans-disposed as a result of symmetry.
