The final unadorned tris(azolyl)borate: finishing what Trofimenko started in 1966

Abstract

The final addition to the tris(azolyl)borate ligand family, tris(1,2,3-triazolyl)borate, has been synthesized. The sodium salt of the ligand forms a complex polymeric structure where both N2 and N3 bind to crystallographically independent sodium ions. Depending on the divalent transition metal, tris(1,2,3-triazolyl)borate forms either molecular homoleptic complexes or coordination polymers.
