FIR.‐Spektren von Übergangsmetallkomplexen mit orthogonalem Ligandensystem. I. Halogeno‐Kupfer(II)‐Komplexe methylsubstituierter Pyridine

Far-infrared spectra (400–40 cm−1) have been studied for orthogonal systems CuL2X2 (L = pyridine, mono-, di-, tri-methylsubstituted pyridine and X = Cl, Br). Assignements are suggested for the four bands of the molecular vibrations which form a stable region within the spectra of the complex series. Relations between number and position of bands and structural data are discussed.
