The image shows hexagonal Pd nanocrystals formed from hexagonal Pd 2 (dba) 3 microcrystals. As‐grown hexagonal platelets formed from a Pd 2 (dba) 3 precursor are shown to be disordered microcrystals containing 1–2 nm Pd clusters, which grow and transform into Pd nanocrystals under an electron beam or through thermal annealing. In‐depth investigation of the crystal structure and transformation process are presented by James J. De Yoreo, Stefan Franzen and co‐workers on page 280.
