Abstract

Aerial recrystallization of the mononuclear molybdenum(V) complex {HB(Me₂pz)₃}MoO(OC₆H₄-o-S) produced the novel binuclear Mo(VI) complex [{HB(Me₂pz)₃}MoO₂(OC₆H₄- o-S)]₂ which contains a disulfide bond. The dimer crystallizes as the dioxane solvate in the space group C2/c with cell parameters a=23.46(2), b=11.100(4), c=21.571(8) Å, β=104.23(4)°, Z=4. Final R_w=0.062 (2236 reflections with F_o>3σ(F_o), 301 variable parameters). The dimer contains two crystallographically identical distorted octahedral MoO₂²⁺ centers. One face of each octahedron is occupied by two oxo ligands and a phenolate oxygen atom; the opposite face is occupied by three nitrogens of the HB(Me₂pz)₃^- ligand. The two Mo(VI) centers of the dimers are linked by a disulfide bond formed upon oxidation of the 2-mercaptophenolate ligand of the original molybdenum(V) compound.
