LiBiO2: a model for Bi3+ co-ordination in high temperature superconductors
Abstract
The structure of LiBiO2, determined by powder neutron diffraction, contains adjacent rocksalt-related BiO layers similar to those found in superconducting phases, but the simpler composition has allowed reliable determination of the Bi3+ co-ordination (pyramidal with Bi–O bonds of 2.038, 2.096, and 2.130 Å).
