Abstract: The title compound, dicerium triruthenium pentadecaaluminium, is a new intermetallic compound from the Al-rich region of the Ce-Ru-Al phase diagram. Two Ce atoms (6g and 2a sites of space group P6₃/mcm) are coordinated by 18 atoms, one Ru atom (12i site) and five Al atoms (12k, 12i, 12j, 12j and 12k sites) have 12 nearest neighbours each.
