The structure of the recently reported transparent conductor, Ga3-xIn5+xSn2O16(0.3<x<1.6), was established by a combination of high-resolution electron microscopy, convergent-beam electron diffraction, and Rietveld analysis of powder diffraction data (X-ray and time-of-flight neutron methods). This "T-phase" compound has an anion-deficient fluorite-derivative structure whose space group isI41/a. Although there are similarities to the parent oxide structures, the T-phase lacks one of the distorted InO6octahedra observed in In2O3, which may account for its inability to be donor-doped by Sn.
