Abstract

According to the Rietveld refinements and X-ray absorption studies at the Ru K-edge, it is found that three compounds La₂BRuO₆ (B=Li, Mg, and Zn) are monoclinic with space group of P2₁/n, and that the ruthenium ions with two oxidation states +IV (d⁴) and +V(d³) are stabilized in an octahedral site of oxide lattices. A correlation is obtained between absorption edge position and the oxidation states of ruthenium. The bond lengths of (Ru-O) for both oxidation states (Ru^IV and Ru^V) have been quantitatively obtained by the EXAFS analysis.
