Abstract

Disorder in the X-ray structures of [Ru₃(CO)₁₀{P(OⁱPr)₃}₂] (3) and [Ru₃(CO)₉{P(OⁱPr)₃}₃] (4) has been examined. Both structures show a "Star of David" disorder of the Ru₃ triangle. The amount of disorder on the Ru₃ triangle is temperature dependent, where the ligands hardly move, indicating that the whole cluster does not rotate intact in the crystal lattice but rather the Ru₃ triangle effectively oscillates within a relatively rigid ligand polyhedron. The space-group of 4 at 273 K is P2(1)/n changing to P2(1) upon cooling to 100 K.
