Abstract

The reaction of Ru₃(CO)₁₂ with Ga₂Cl₄ in the presence of gallium metal in refluxing toluene, followed by crystallization from tetrahydrofuran, produces Ru{GaCl(THF)₂}{GaCl₂(THF)}₂(CO) ₃·0.5 THF (1) and Ru₂{GaCl₂-(THF)}₂(CO)₈ (2) (THF = tetrahydrofuran). The ruthenium atom in 1 has an approximately octahedral coordination environment, with meridinal arrangements of carbonyl ligands and gallium atoms. The GaCl(THF)₂ group is in a position trans to one of the GaCl₂(THF) groups. The crystal structure of 2 consists of a linear arrangement of metal atoms in which two GaCl₂(THF) groups are in axial positions with respect to the metal-metal bond of an Ru₂(CO)₈ unit. Crystal data for 1: monoclinic space group P2₁\c (No. 14), a = 17.367(3) Å, b = 12.054(2) Å, c = 16.049(3) Å, β= 95.18(1)°, Z = 4, R = 0.0527, R_W = 0.0718. Crystal data for 2: monoclinic space group P2₁/c (No. 14), a = 11.980(1) Å, b = 6.944(1) Å, c = 16.097(3) Å, β = 96.81(1)°, Z= 2, R = 0.0300, R_W = 0.0510. The title complexes are the first compounds to contain ruthenium-gallium bonds, and compound 1 is the second structurally-characterized example of a complex in which a gallium(I) species is terminally coordinated to a transition metal.
