Abstract
The X-ray powder pattern of the Pb-free 110 K superconductor phase Bi2Sr2Ca2Cu3Ozhas many lines which belong to an incommensurate supercell. Using electron diffraction photographs as a guide, an indexing scheme for the powder pattern has been obtained. The unit cell has a geometrically orthorhombic subcell a = 5.411(2), b = 5.420(2), c = 37.29(2) A. Superce11 reflections have indices that are derived from the subcell k, l indices by addition of ± q*, where q* = n<5b* + nec* : n = 1, 2 …; 5 = 0.211(2); ∊= - 0.78(1).
