Abstract The infrared spectra of thiocyanato-copper(II) complexes of the type Cu(NCS)2 L 2 with all isomeric picolines and lutidines (L) as well as those of the type Cu(NCS)2 L 3 withL=3- and 4-picoline, 3,4- and 3,5-lutidine were measured. The behaviour of the ν (CN) stretching vibrations of the Cu(NCS)2 L 2 complexes led to conclusions on the different kind of coordination of the NCS groups in dependence on the ligandL. The mutually conditioned strength of the Cu−NCS and Cu−N(L) bonds in the equatorial plane, especially in the presence of ligandsL with the steric effect, was determined from the frequency shift of the Cu−NCS and Cu−N(L) stretching vibrations with regard to the vibrations for Cu(NCS)2(pyridine)2.
