Abstract
X-ray L3 absorption spectra of Pr and the crystallochemical characteristics of the PrFe10Mo2 and PrNi5 intermetallic compounds have been studied. It has been shown for the first time that atoms of Pr, similar to those of Ce, can reside in a mixed valence state. The valency of praseodymium is +3.08 ± 0.03 and +3.10 ± 0.03 in PrFe10Mo2 and PrNi5, respectively. The mixed valence state of Pr disappears when one Ni atom in PrNi5 is replaced by Al or Ga. The nature of the quadrivalent state of Pr in intermetallic compounds is discussed.
