Abstract

The action of PhI·Cl₂ on W₂Cl₄(PMe₃)₄ in 1:1 mole ratio gives brown 1,3,6-W₂Cl₅(PMe₃)₃. The EPR at 10 K in frozen CH₂Cl₂ solution has a broad signal at g = 1.83. The molecular structure was determined by X-ray crystallography and shows a W-W distance of 2.291(1) Å, about 0.03 Å longer than that in W₂Cl₄(PMe₃)₄ Crystal data: monoclinic space group C2/c with cell dimensions of a = 13.423(2) Å, b = 12.0768(9) Å, c = 28.247(5) Å,β = 93.360(7)°, V = 4571(1) Å³, and Z = 8. There is a 1.8% orientational disorder. When a solution of W₂Cl₆(PMe₃)₄ in CH₂Cl₂ plus hexanes was allowed to stand at −15 ·C for several months, brown crystals of [HPMe₃]₂[W₂Cl₈(PMe₃)CH₂Cl₂ were obtained. The anion is a face-sharing bioctahedron, with a W-W bond length of 2.433(1) Å. Crystal data: monoclinic space group P2₁lm with cell dimensions of a = 9.398(1) Å,b = 9.836(2) Å, c = 16.687(5) Å, β = 97.78(2)°, V = 1528.4(6) Å³, and Z = 2.
