摘要：
The structure and the oxygen stoichiometry of the layered oxide BiPbSr2MnO6 has been examined by profile analysis from powder neutron diffraction data. The structure was refined in the space group Amaa (n degrees 66). The material has orthorhombic symmetry with lattice parameters a=5.3204(3), b=5.3796(3) and c=23.714(1)Angstrom. Its structure is analogue to that of superconducting cuprate Bi2Sr2CuO6+delta, but without modulation. An important structural feature of BiPbSr2MnO6 is that the oxygens in the (Bi,Pb)O layer are disordered over two positions along the a-axis. The calculated effective valence of manganese is 3.2. The MnO6 octahedra are elongated along the c-axis, characteristic of the Jahn-Teller distortion of octahedra with Mn3+ ions.
