Abstract

Treatment of [MCl(NNRR′₂(PPh₃)₂]Cl (M = Mo or W; R,R′ = Me₂ or Me, Ph) with [{Fe(CO)₃(μ₂-SLi)}₂](Fe-Fe) gives the trinuclear clusters [{Fe(CO)₃(μ₃-S)}₂M(NNRR′)₂(PPh₃)](Fe-Fe) in good yield. The X-ray crystal structure of [{Fe(CO)₃(μ₃-S)}₂Mo(NNMe₂)₂(PPh₃)] · CH₂Cl₂ (space group P2₁2₁2₁,; a 15.089(4), b 15.569(5), c 16.983(4) Å; Z = 4; R = 0.061 for 1915 observed reflections) confirms the absence of iron-molybdenum bonding, and the complexes generally show similar Mössbauer parameters. Analogous coordination environments at molybdenum are obtained in [Mo(NNMePh)₂(C₇H₆S₂)(PPh₃)] (C₇H₆(SH)₂ = 3,4-dimercaptotoluene) and in the dimeric species [{Mo(NNMePh)₂-(μ₂-S)(PPh₃)}₂]. These are prepared by reaction of [MoCl(NNMePh)₂(PPh₃)₂]Cl with 3,4-dimercaptotoluene and S(SiMe₃)₂, respectively.
