Structural Aspects

Raman and FTIR spectra of KMg1/3Nb2/3PO5 (KMNP) crystal are recorded. The observed bands are assigned mainly in terms of vibrations of NbO6 octahedra and PO4 tetrahedra. The NbO6 octahedra in the crystal are distorted. Corner shared octahedra are present in the KMNP structure. The intense ν1 band at 890 cm-1 in the Raman spectra indicates an ordering in the crystal. The TiO6 octahedra in KTP crystal are more distorted than those of NbO6 octahedra in KMNP. The presence of Mg ions disrupts Nb–O–Nb chains leading to a distortion of NbO6 octahedra different from that of TiO6 . The PO4 tetrahedra in the crystal are linearly distorted. No structural phase transition is observed in the crystal when temperature is lowered to 77 K.
