Abstract New praseodymium complexes of 2,6-lutidine, 4-methoxy-2,6-lutidine and 3-halo-2,6-lutidine N -oxides (LuO) have been synthesised and chemically characterised. The Fourier transform IR and Raman spectra have been measured in the range 50–4000 and 80–4000 cm −1 , respectively, and discussed in terms of possible structure and composition of compounds studied. The frequencies of the stretching
