Abstract

The purpose of this thesis is to synthesize Au₁₄₄(SCH₂CH₂Ph)₆₀ using a two-step synthesis reaction, and then using this product to conduct a core conversion from Au₁₄₄(SCH₂CH₂Ph)₆₀ to Au₉₉(SPh-CH₃)₄₂. The Au₉₉(SPh-CH₃)₄₂ product will then be used to attempt to form crystals using five different crystal set-up methods. Au₁₄₄(SCH₂CH₂Ph)₆₀ is made with aliphatic thiolate ligands, and when it is placed in a mixture containing excess para-methyl benzenethiol, it undergoes a core-conversion to Au₉₉(SPh-CH₃)₄₂. This is a relatively new nanoparticle, and it is being used to hopefully form crystals which can, in turn, give information about its structure. The crystallization was unsuccessful with the five different set-ups employed, but the Au₉₉(SPh-CH₃)₄₂ structure is still being studied with the hopeful crystal structure being found soon.
