In this work, we report the synthesis and detailed structural characterization of novel helical gold–copper nanowires. The nanowires possess the Boerdijk–Coxeter–Bernal structure, based on the pile up of octahedral, icosahedral, and/or decahedral seeds. They are self-assembled into a coiled manner as individual wires or into a parallel-ordering way as groups of wires. The helical nanowires are ultrathin with a diameter of less than 10 nm and variable length of several micrometers, presenting a high density of twin boundaries and stacking faults. To the best of our knowledge, such gold–copper nanowires have never been reported previously.
