Structure and Ionic Conductivity of Li-Disordered Bismuth o-Thiophosphate Li_60-3xBi_16+x(PS₄)₃₆.

ABSTRACT: The structure of the first lithium-containing bismuth ortho (o)-thiophosphate was determined using a combination of powder X-ray, neutron, and electron diffraction. Li_60-3xBi_16+x(PS₄)₃₆ with x in the range of 4.1-6.5 possesses a complex monoclinic structure [space group C2/c (No. 15)] and a large unit cell with the lattice parameters a = 15.4866 Å, b = 10.3232 Å, c = 33.8046 Å, and β = 85.395° for Li_44.4Bi_21.2(PS₄)₃₆, in agreement with the structure as observed by X-ray and neutron pair distribution function analysis. The disordered distribution of lithium ions within the interstices of the dense host structure and the Li ion dynamics and di
