We report the X-ray crystal structure of Au₃₆₋ₓAgₓ(SPh-tBu)₂₄ alloy nanomolecules, optical properties, and the substitutional disorder refinement protocol to obtain a reliable structural model. Single crystal X-ray crystallography (SC-XRD) revealed a composition of Au₃₃.₁₇Ag₂.₈₃(SPh-tBu)₂₄ with 2 Ag...
