Synthesis and molecular structure of a spheroidal binary nanoscale copper sulfide cluster†
Abstract
The reaction of copper(4-(tert-butyl)phenyl)methanethiolate [CuSCH2C6H4tBu] with bis(trimethylsilyl)sulfide S(SiMe3)2 in the presence of triphenylphosphine PPh3 afforded the binary 52 nuclear copper cluster [Cu52S12(SCH2C6H4tBu)28(PPh3)8]. The molecular structure of this intensely red coloured nanoscale Cu2S mimic was established by single crystal X-ray diffraction.
