The first C 3 ‐symmetric 44‐core‐valence‐electron triangular palladium clusters, [{(SAr′)(PAr 3 )Pd} 3 ] + , have been synthesized by activation of the CS bond of isothioureas. Owing to delocalized metal–metal bonding, these stable complexes are the first noble‐metal analogues of the π‐aromatic cyclopropenyl cation [C 3 H 3 ] + , with their all‐metal aromaticity involving d‐type atomic orbitals.
