The valence state of the Cr ion in Ca-doped lanthanum chromite compounds without or with oxygen deficiency has been calculated by means of a tight-binding approximation on the basis of the EHMO approximation. The results indicate that the relative content of Cr 4 ions in La 1ร€x Ca x CrO 3 will becom
