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.
