Summary
Compounds with the composition CuXL, in which X=Cl− or Br− and L=R,S-1-amino-2-propanol andS-1-amino-2-propanol, both with deprotonated hydroxy groups, are described. Magnetic measurements strongly suggest these compounds to have a tetrameric cubane-type structure with a Cu4O4 core. The racemic and optically-active compounds show a different magnetic behaviour, most likely originating from different cluster types for the isomers. The results of the i.r., f.i.r. and e.s.r. spectra are in good agreement with the proposed cluster types.
