Description

The crystal structure of stage-1 iodine-intercalated superconducting I(Bi0.915, Pb0.085)2(Sr0.93, Pb0.07)2(Ca0.965, Pb0.035)2Cu3Ox has been determined by transmission electron microscopy to belong to the space group Pma2 with lattice parameters a=5.4 A, b=5.4 A, and c=22.0 A. Iodine atoms intercalated as monolayers between every Bi-O bilayer alter the atomic stacking across Bi-O layers from the staggered configuration characteristic of superconducting (Bi0.915, Pb0.085)2(Sr0.93, Pb0.07)2(Ca0.965, Pb0.035)2Cu3Ox to a vertically aligned configuration in I(Bi0.915, Pb0.085)2(Sr0.93, Pb0.07)2(Ca0.965, Pb0.035)2Cu3Ox. Iodine bilayers have also been observed to form between Bi-O layers, yielding a new series of stage-n iodine-intercalated compounds. (orig.)
