Abstract:
Density functional theory and infrared spectroscopy were used to determine the structure of N,O-dilithio-2-(N-methylamino)ethanol, a mixed intramolecular aggregate. The calculations indicated that the cyclic form of this compound is more stable than the open form, and that conclusion is consistent with the infrared spectra. The solid-state spectra showed lower Li-N and Li-O vibrational frequencies than were calculated for the gas phase, which is consistent with coordination of lithium to electronegative atoms on adjacent molecules in the solid state.
