Colloidal nanoparticles of a prototype polar intermetallic compound, Au 3 Li, were synthesized by reacting Au nanoparticle seeds with n ‐butyllithium. X‐ray and electron diffraction data are consistent with the L 1 2 (Cu 3 Au) structure type expected for Au 3 Li. Composition analysis indicates a stoichiometry of approximately Au 3 Li 0.7 , which is within the reported composition range of the Au 3 Li phase. The Au 3 Li nanoparticles decompose in water to regenerate Au. The successful synthesis of Au 3 Li as colloidal nanoparticles demonstrates that polar intermetallic compounds containing highly electropositive elements are accessible by using low‐temperature solution chemistry routes and that they are also amenable to nanostructuring.
