The neodymium monochloroacetate complex was obtained in the form of monocrystal. The absorption and emission spectra for this single crystal were recorded at room and low temperatures down to 4.2 K. Intensities of electronic lines and Judd–Ofelt parameters were calculated. Splitting and energies of electronic levels were considered and compared to those for the neodymium trichloroacetate single crystals. The covalent effect in the spectra was discussed. The results obtained from the low temperature spectra for [{Nd(ClH
