The preparation and properties of four new compounds are reported. These are [Ru3Cl6(PEt3)6] [RuCl4(PEt3)2] (1), [Ru3Cl6- (PBu3)6] [RuCl4(PBU3)2] (2), [Ru3Cl6(PBu3)][BPh4] (3), and [Ru3Cl6(PEt3)6][BPh4] (4). All of these contain a new type of derivative of the [Ru3Cl12]4- ion in which all six terminal chloride ligands are replaced by phosphines and a one-electron reduction has occurred. The first three of these new compounds have been characterized by X-ray crystallography, with the following results: 1, triclinic, space group P1, a = 10.669 (4) ?, b = 17.682 (6) ?, c = 10.495 (3) ?, α = 90.33 (2)°, β = 109.11 (2)°, γ = 99.14 (3)°, V = 1844 (2) ?3, Z = 1, Ru-Ru = 3.085 (1) ?; 2, monoclinic, space group P21/n, a = 13.490 (2) ?, b = 21.331 (6) ?, c = 23.055 (6) ?, β = 99.53 (2)°, V= 6542 (3) ?3, Z = 2, Ru-Ru = 3.083 (1) ?; 3, triclinic, space group P1, a = 19.694 (4) ?, b = 23.193 (4) ?, c = 13.224 (2) ?, α = 91.96 (1)°, β = 106.34 (2)°, γ = 100.78 (3)°, V= 5670 (4) ?3, Z = 2, Ru-Ru = 3.078 (1)?.
