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 Rw=0.062 (2236 reflections with Fo>3σ(Fo), 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.
