Abstract

In this paper, we report the first synthesis and characterisations of bimetallic gold(I)–silver(I) calix[8]arene complexes. We show that the radiolytic reduction of these complexes leads to the formation of small bimetallic nanoparticles with an alloyed structure, as evidenced by XPS, HR-TEM and STEM/HAADF-EDX measurements.
