Sodium tetralactamatoaluminate(1-) complexes have been prepared by reaction of sodium tetraamidoaluminate with 4-butanelactame, 6-hexanelactame, and 12-dodecanelactame, and their infrared spectra have been measured in the region from 600 to 4 000 cm-1. For assignment of some bands, a series of sodium 6-hexanelactamato-isobutylaluminates(1-) and 2-methoxyethoxo-lactamatoaluminates(1-) have been prepared. The bands in the region 1550-1650 cm-1 are discussed.
