✦ Synopsis

A model is proposed for the superstructure of Bi2Sr2CaCu2Os.2. It involves the addition of one in ten oxygen atoms in the BiO planes and a displacement of the surrounding atoms. This model is consistent with electron microscope, neutron and X-ray diffraction data. In particular it is consistent with the symmetry determined by convergent beam electron diffraction and with details of the high resolution electron microscope image contrast.
