摘要：

The effects of high pressure on Cs2CuCl4, bis(trimethylbenzylammonium) tetrachlorocuprate, (N-phenylpiperazinium) tetrachlorocuprate, bis(N-benzylpiperazinium) tetrachlorocuprate bis(hydrochloride), and bis(N-methylphenethylammonium) tetrachlorocuprate are reported. Electronic spectroscopy indicates molecular rearrangements in the tetrachlorocuprate ions with increasing pressure. The changes in geometry and nature of the rearrangements are discussed. The general result is that at high pressure there is a considerably smaller range of dihedral angles for the five complexes. The results are considered in the context of stereochemical structural pathways for copper(II) systems. © 1990 American Chemical Society.
