Abstract

Reaction of NH((PPr2)-Pr-i)(2) with elemental selenium in concentrated solvent conditions enables large scale preparation and improved yields of NH((PSePr2)-Pr-i)(2) that may be deprotonated with sodium methoxide to give NaN((PSePr2)-Pr-i)(2). Treatment of the sodium salt with appropriate Group 11 metal salts in methanol yields a range of trinuclear complexes. The protic solvent conditions utilized facilitate the reduction of copper(II) salts resulting in the isolation of copper( I) complexes. These new Group 11 complexes have been characterised by H-1 and P-31 NMR and IR spectroscopy, APCI mass spectrometry, microanalysis and X-ray crystallography. Thermolytic decomposition of the copper( I) precursors in the presence of the indium precursor, In[((SePPr2)-Pr-i)(2)N](2)Cl, has been carried in the solid state using AA-MOCVD to give copper indium diselenide solid state materials CuInSe2.
