The material structure described by Pr2PbS4 crystallizes in the tetragonal I-42d space group. Pr(1) is bonded to eight equivalent S(1) atoms to form a mixture of distorted corner, face, and edge-sharing PrS8 hexagonal bipyramids. Pb(1) is bonded in a 8-coordinate geometry to eight equivalent S(1) atoms. S(1) is bonded in a 6-coordinate geometry to four equivalent Pr(1) and two equivalent Pb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
