The copper(I) compounds [Cu(dppe) 2 ]X [X = BF 4 − , I − ; dppe = 1,2‐bis(diphenylphosphanyl)ethane], [Cu(dppp) 2 ]X [X = BF 4 − ,I − ; dppp = 1,3‐bis(diphenylphosphanyl)propane], [Cu 2 (dppe) 3 I 2 ], and [Cu 2 (dppe) 2 I 2 ] have been prepared and their structural properties in solution and in the solid state have been determined. 1 H‐, 13 C‐, and 31 P‐NMR spectra in solution [variable temperature and anion (I − ) concentrations] and analyses of solids (mass spectra, elemental analyses, and CPMAS 31 P‐NMR spectra) are interpreted with equilibria in solution that involve two mono‐ and two dinuclear species. The structures of [Cu(dppe) 2 ]ClO 4 , [Cu(dppp) 2 ]BF 4 , and [Cu 2 (dppe) 3 I 2 ] · 2 CHCl 3 have been analyzed by X‐ray crystallography. In all three structures the copper(I) center adopts a distorted tetrahedral geometry.
