Abstract
The mononuclear molybdenum complex [Mo(HL)2] (1), Mo–Mo single-bond compound [HLClMo(µ-Cl)3MoHLCl] [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 ofHL {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 ligandHL 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.
