We report double s-aromaticity in a surface-deposited cluster, Pd4 , on the
TiO2 (110) surface. In the gas phase, Pd4 adopts a tetrahedral structure. However, surface binding promotes a flat, s-aromatic cluster. This is the first time aromaticity has been found in surface-deposited clusters. The concept of aromaticity is expected to become instrumental in predicting and interpreting properties of such systems, much like it is for isolated molecules and clusters.
