Abstract

The X-ray powder pattern of the Pb-free 110 K superconductor phase Bi2Sr2Ca2Cu3Oz has 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) Å. Supercell reflections have indices that are derived from the subcell k, l indices by addition of ± q, where q = nδb + nεc: n = 1,2 …; ε = 0.211(2); ε = −0.78(1).
