i	68.6	2.59 ± 1.15	~Pd₅₈₆L₁₄₂	0.52
ii	51.0	1.51 ± 0.46	~Pd₁₁₆L₅₉	0.75
iii	55.7	1.66 ± 0.62	~Pd₁₄₀L₅₉	0.61

v	80.6	3.38 ± 0.95	~Pd₁₂₈₉L₁₆₄	0.34

Average core size was calculated from histogram analysis of TEM images.

Calculations were based on theoretical model of a truncoctahedron.⁴¹

Ligand surface coverage was calculated by dividing the total ligands by surface Pd atoms of PdNP.
