Spectroscopic and Computational Investigation of Low-Spin Mn(III) Bis(scorpionate) Complexes.

ABSTRACT: Six-coordinate Mn^III complexes are typically high-spin (S = 2), however, the scorpionate ligand, both in its traditional, hydridotris(pyrazolyl)borate form, Tp^- and Tp*^- (the latter with 3,5-dimethylpyrazole substituents) and in an aryltris(carbene)borate (i.e., N-heterocyclic carbene, NHC) form, [Ph(MeIm)₃B]^-, (MeIm = 3-methylimidazole) lead to formation of bis(scorpionate) complexes of Mn^III with spin triplet ground states; three of which were investigated herein: [Tp₂Mn]SbF₆ (1SBF₆), [Tp*₂Mn]SbF₆ (2SBF₆), and [{Ph(MeIm)₃B}₂Mn]CF₃SO₃ (3CF₃SO₃).
