Two {110}-faceted gold nanostructuresrhombic dodecahedra and obtuse triangular bipyramidshave been synthesized via a Ag-assisted, seed-mediated growth method. The combination of a Cl-containing surfactant with a low concentration of Ag+ plays a role in the stabilization of the {110} facets. To the best of our knowledge, this is the first reported synthesis of a {110}-faceted bipyramid structure.
