63 Cu‐NMR.‐Spectra of Cu(CH 3 CN) 4 X (X = ClO − 4 , BF − 4 , PF − 6 ) and Cu(C 5 H 5 N) 4 X (X = ClO − 4 , BF − 4 ) in solution are reported at different temperatures and concentrations. The influence of temperature on the linewidth and chemical shift indicates an equilibrium of Cu(CH 3 CN) + 4and Cu(C 5 H 5 N) + 4with another complex of lower symmetry. The preferential solvation of Cu (I) by pyridin in a mixture acetonitrile/pyridine is clearly shown.
