We report for the first time the interconversion between two nanomolecules: Au36(SPhX)24, (where X = -H or -tBu) and Au30(S-tBu)18. This is accomplished through thermochemical etching, with HSPhX on Au30(S-tBu)18 which converts the nanomolecule to Au36(SPhX)24. We further show that the conversion is...
