Layered materials composed of silver−alkanethiolate units are characterized and compared to self-assembled alkanethiolate monolayers thiolate-capped nanoparticles. A comprehensive infrared spectroscopy study is presented for having chain lengths varying from 7 18 carbon atoms (AgSC7 AgSC18). The high level definition in these spectra will make this a benchmark system comparisons other metal thiolate systems. An X-ray diffraction same used determine the tilt angle chains (12 ± 3°), which very close that reported on Ag(111). These results combined with thorough characterization AgSC12 material using photoelectron spectroscopy, electronic differential scanning calorimetry, solid-state NMR. Overall, provides detailed description structure, thermal stability, degree conformational order materials, have not previously been extensively at lengths.
