A powder neutron diffraction study has been undertaken for the titled compounds at room temperature. Data were analyzed using the Rietveld method. With increasing Nd content the unit cell has been found to contract very slightly, which is in accordance with the ionic radii of La3+ and Nd3+.

The powder neutron diffraction pattern of pyrolusite, β-MnO2 [P42/mnm, No. 136, a = 4.4041(1), c = 2.8765(1)Ǻ], has been refined by the Rietveld method to give values for both the oxygen position parameter u=0.3046(1) and the anisotropic thermal parameters. The data confirm the MnO6 octahedra to be elongated with two long [1.894(1)Ǻ] and four short [1.882(2)Ǻ] Mn-O bond distances. The effect of the stereochemistry on the thermal vibrations is discussed.
