Abstract
Confirmation of the far infrared (500–200 K) spectroscopic assignments of the metal–ligand vibrations in the complexes Cu(N–N)2X2 and Cu(N–N)X2((N–N) = ethylenediamine, symmetric and asymmetric N,N-dimethyl- and N,N-diethylethylenediamine, X = Cl, Br, NO3) has been obtained from copper isotopic substitution measurements. Extension of the series Cu(ethylenediamine)2X2 has provided some exceptions to the straight line correlation between [v(Cu—N)]2 and mean electronic d–d band energy. These are discussed.Keywords
