The title complex, [RuBr2(C5H5N)4], contains two independent complex molecules in each of which the RuII 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.
