Based on the density functional theory, we demonstrate that Aun (n=4–7) can have stabilized configurations such as like-ring and three dimensional (3D) clusters. Au4 adopt the square geometry with the D4h space group. The Au6 hexagonal cluster seems to be more stable than all other geometries with a zero magnetic moment. A new 3D Au6 can be retrieved with a slight difference in binding energy compared with the cyclic one.
