R_Pd−Au (Å)			2.75 (17)
R_Au−Au (Å)		2.84 (19)	2.84 (18)
σ²_Pd−Pd (Å²)	0.0058 (58)		0.0060 (6)
σ²_Pd−Au (Å²)		0.0077 (72)	0.0039 (4)
σ²_Au−Au (Å²)			0.0088 (9)

^aValue fixed for calculation.

^bCoordination numbers were constrained in the fits to be varied in accordance with equation: N_Pd−Au/N_Au−Pd = X_Au/X_Pd.

^cN_M−M = X_AuN_Au−M + X_PdN_Pd−M (where X_Au and X_Pd are the molar composition of Au and Pd, respectively).
