Chemistry of copper(I) .beta.-diketonate complexes. 2. Synthesis, characterization, and physical properties of (.beta.-diketonato)copper(I) trimethylphosphine and bis(trimethylphosphine) complexes

The volatile copper(I) complexes (β-diketonate)Cu(PMe 3 ) n where β-diketonate=hexafluoroacetylacetonate (hfac), trifluoroacetylacetonate (tfac), and acetylacetonate (acac) for n=1 and 2 and β-diketonate=dipivaloylmethanate (dpm) and dibenzoylmethanate (dbm) for n=1 have been prepared in high yield. These species have been characterized by spectroscopy,by elemental analysis and by single-crystal X-ray diffraction
