Times Cited Count:55 Percentile:79.06(Chemistry, Multidisciplinary)A-site-ordered perovskites LaMnCrO and LaMnTiO were synthesized under high-pressure and high-temperature conditions. The charge formula of LaMnCrO was found to be LaMnCrO with Mn at the square-coordinated A site. The valence of the A-site Mn ions in LaMnTiO appeared to be less than +2, and the charge combination in this compound seemed to be LaMnTiO. Although the square-coordinated A site in A-site-ordered perovskites has been widely known to be occupied by Jahn-Teller active Mn, the present results show that the valence of Mn at the A site can vary from +3 to possible +1.67.
