In this paper, a comparative study of the XRD characterization and FTIR spectroscopic behavior of some MILnIIITiO4phases with MI: Na, H, K and LnIII, the trivalent lanthanides elements: Sm, Eu, Er and Yb is reported. The H and K- oxides wereobtained by ion-exchange from NaLnTiO4. These ternary oxides belong to the K2NiF4 structural type, with the MI and LnIII cationsdistributed in an ordered way on the K-sub lattice. The FTIR spectra of the materials were analyzed by comparison with structurallyrelated materials. A close relationship with the parent NaLnTiO4 was found.
