title: Au(144-x)Pd(x)(SR)60 nanomolecules.
abstract: Au144-xPdx(SR)60 alloy nanomolecules were synthesized and characterized by ESI mass spectrometry to atomic precision. The number of Pd atoms can be varied by changing the incoming metal ratio and plateaus at 7 Pd atoms. Based on the proposed 3-shell structure of Au144(SR)60, we hypothesize that the Pd atoms are selectively incorporated into the central Au12 icosahedral core.
