Far Infrared Spectra

The infrared and Raman spectra of [Et3PcuI]4 and [Et3AsCuI]4 have been measured, and bands have been assigned to vibrations of the ligand and of the Td Cu4I4 core. The far-infrared spectra show two strong T2 v(CuI) bands at about 90 and 140 cm-1, the higher frequency member of which has a Raman counterpart which shows possible longitudinal-transverse splitting. The Raman spectra also show an intense band at about 50 cm-1. Similar features have been observed in the low-frequency vibrational spectra of [Et2S]3 [CuI]4, [C5H5NcuI]4, [C5H11NAgI]4, [Et3PAgBr]4 and [Et3PagCl]4, although the last two compounds gave only a single broad band in the v(MX) region.

Far Infrared Spectra

A number of different methods for preparing anionic Group 1B metal thiolate complexes have been investigated. The compounds [Me4N] [CU2(SMe)3] and [Et4N] [Ag5(SBut)6] are reported for the first time, and new methods for preparing the previously known compounds [Et4N] [Cu5(SBut)6], [Me4N]2 [CU5(SPh)7] and [Et4N]2 [Cu5(SPh)7] are described. The far-infrared spectra of the above compounds, and of CuSMe, CuSBut, AgSBut, [Me4N]2 [CU4(SPh)6] and [Me4N]2 [Ag5(SPh)7] have been obtained, and metal-sulfur stretching bands are assigned in the 150-350 cm-1 region. The low-frequency Raman spectra have also been obtained for some of these compounds. Possible structures for the new compounds are considered in the light of the low-frequency vibrational spectra.
