Abstrakt: 1.The PMR and13C NMR spectra of a number of derivatives of dibenzenechromium, as well as bis-(ethylbenzene)molybdenum, were investigated.2.In the case of coordination with a metal, the signals of the aromatic protons and carbon atoms of the benzene ring experience a substantial strong-field shift in comparison with the free arenes (by 2.5–3 ppm in the PMR spectra and by ~50 ppm in the13C NMR spectra).
