ALT An illustration of a density functional theory relaxed unit cell of ω-lithium thiophosphate with fully occupied d and b Wyckhoff sites and empty c sites shown as dashed black circles. On the right is a legend showing Li as a green sphere, PS4^-3 as a purple triangular prism with yellow spheres at the points, P5 as a purple sphere, S2- as a yellow sphere, and a dashed black circle as an empty site. The unit cell features four triangular prisms and 12 green spheres.
