Abstract

The binuclear cycloplatinated complex {[Pt(L)]₂(μ-dppm)}²⁺ (1), where HL is a new cyclometalating ligand 2-phenyl-6-(1H-pyrazol-3-yl)pyridine, is found to behave as a molecular pivot-hinge in which the closing and opening of the hinge is effected by the reversible formation and cleavage of the Pt-Pt d⁸-d⁸ interaction and the intramolecular π-π interaction mediated by the protonation/deprotonation of the 1-pyrazolyl-NH on the cyclometalating ligand L.
