Possible morphologies of Au Nanoparticles – Rhombic dodecahedron

Compare the idealised polyhedron structure with the structures calculated for various numbers of gold atoms by Density Functional Theory.

This structure can be truncated from the cube. Also, it can be further truncated into octo-truncated rhombic dodecahedron. Large size nanoparticles may adopt this shape.

These hypothetical structures are presented for comparison.
