Development of a novel scorpionate ligand with 6-methylpyridine and comparison of the structural and electronic properties of nickel(ii) complexes with related tris(azolyl)borates

Abstract

A novel anionic tridentate borate ligand with a 6-methylpyridyl donor, Tpy^Me, has been synthesized. Comparison of the molecular structures and reactivities of nickel(II)-bromido complexes with tris(azolyl)borate ligands composed of pyridyl, pyrazolyl, or oxazolinyl donors indicates the characteristic sterically demanding nature and strong electron donating ability of Tpy^Me.
