Preparation and Ionic Substitution of Dion-Jacobson Type Compounds CsLa(M,Mn)_nO_(3n+1)(M=Nb, Ta; n=2,3)

摘要

Dion-Jacobson type compound, CsLa_2NbMn_2O_(10), containing Mn ion as a transition metal was prepared by a conventional solid state reaction for the first time. Cesium ions in this compound can be exchanged by lithium ions. Crystal structure of new compound, CsLa_2NbMn_2O_(10), was estimated by simulation of X-ray diffraction pattern. Lithium ion-exchange changes the space group of this layered perovskite from P4/mmm to body-center I4/mmm.
