IR-specters and nature of oxygen and nitrogen containing complexes of tetra-hydro borates of rare-earth metals

This work reports the spectral (infrared Raman) characterization of the series of complex compounds M(BH₄)₃∙3 THF and M(BH₄)₃∙3 L, where M-lanthanides; L-N₂H₄, C₄H₈N₂. Vibration spectra indicates that the mode of BH₄-coordination is sensitive to the metal ionic. All data suggest character in boarding of the tetra-hydro borate ligand to the trivalent lanthanides. Also it was showed the type of coordination ligands and structures of these compounds. (author)
