We report on hexagonal close‐packed (hcp) palladium (Pd)–boron (B) nanocrystals (NCs) by heavy B doping into face‐centered cubic (fcc) Pd NCs. Scanning transmission electron microscopy–electron energy loss spectroscopy and synchrotron powder X‐ray diffraction measurements demonstrated that the B atoms are homogeneously distributed inside the hcp Pd lattice. The large paramagnetic susceptibility of Pd is significantly suppressed in Pd–B NCs in good agreement with the reduction of density of states at Fermi energy suggested by X‐ray absorption near‐edge structure and theoretical calculations.
