Herein, we report an examination of the reactivity of RSH (R = CH2CH2Ph, n-Bu, n-C12H25) with Cu2+ under anhydrous conditions. These reactions result in the formation of fluorescent “Atlas-sphere”-type copper thiolate nanoclusters, including [Cu12(SR′)6Cl12][(Cu(R′SH))6] (2, R′ = nBu) and [H(THF)2]2[Cu17(SR′′)6Cl13(THF)2(R′′SH)3] (3, R′′ = CH2CH2Ph), which were characterized by X-ray crystallography, electrospray
