Abstract Neutron diffraction study on the structure of Bi₂Sr_1.855Ca_1.145Cu₂O₈ was carried out. Data refinements show that the average subcell structure for Bi₂Sr_1.855Ca_1.145Cu₂O₈ in the best fit of the space group Fmmm and the structure is described by alternate stacking of SrO-CuO₂-Ca-CuO₂-SrO slab and a double BiO layers. An oxygen layer sandwiched by the bismuth layers was confirmed.
