Abstract

The mononuclear molybdenum complex [Mo(^HL)₂] (1), Mo–Mo single-bond compound [^HLClMo(µ-Cl)₃Mo^HLCl] [2; Mo–Mo 2.832(7) Å], and Mo≡Mo triple-bond compounds [Mo₂Cl₂(µ-^HL)₂] [3; Mo–Mo 2.194(6) Å] and [Mo₂Cl₂(µ-Cl)(µ-^HL)Cl₂Na(THF)₃] [4; Mo–Mo 2.167(2) Å] have been synthesized by the reaction of^HL {^HL = [(2,6-iPr₂C₆H₃)NCH]₂} with 0.5, 1, and 2 equiv. of MoCl₅and different amounts of Na metal. In the single-bond compound 2, the α-diimine ligand^HL displays the normal chelating coordination mode. In contrast, the triple-bond compounds 3 and 4 feature the less common bridging mode of α-diimine ligands. Complexes 1–4 have been characterized by X-ray diffraction,¹H and¹³C NMR, IR spectroscopy, elemental analysis, and their electronic structures were studied by EPR and DFT computations.
