A ligand design with a modified naphthyridylamide for achieving the longest EMACs: the 1st single-molecule conductance of an undeca-nickel metal string†
Abstract
Striding to extend the length of metal-atom strings, oligo-α-pyridylamino ligands are modulated with naphthyridyl moieties leading to the undeca-nickel mixed-valence complexes [Ni11(bnatpya)4Cl2]4+ (1) and [Ni11(bnatpya)4Cl2]2+ (2). The first single-molecule conductance measurements of a linear undeca-nickel chain were performed.
