| Abstract: | The X-ray structure of H4Ru4(CO)9(PMe2Ph)P(OC6H4Me-p)3]P(OCH2)3CEt], a chiral cluster complex, has been determined. The complex is triclinic, space group P, a 19.812(7), b 14.299(4), c 10.323(4) Å, α 100.09(3), β 98.18(3), γ 102.23(3)°. The unit cell contains an enantiomeric pair of molecules. The Ru4 core contains two short (av. 2.785 Å) and four long (2.967 Å) RuRu separations with approximate D2d symmetry. RuP separations are 2.254(6) Å to P(OCH2)3CEt], 2.270(6) Å to P(OC6H4Me-p)3] and 2.326(7) Å to PMe2Ph]; all P-donor ligands are trans to short RuRu vectors. |
