C3-Symmetrical lanthanide podates organized by intramolecular trifurcated hydrogen bonds

Abstract

The protonated tripodal podand [L⁶ + H]⁺ forms stable and organized monometallic podates [Ln(L⁶ + H)]⁴⁺ where Ln^III is facially nine-coordinated by three wrapped unsymmetrical tridentate binding units. An unusual trifurcated hydrogen bond assists the organisation of the covalent tripod.
