Pr2Te3 crystallizes in the tetragonal I-42d space group. There are three inequivalent Pr sites. In the first Pr site, Pr(1) is bonded to two equivalent Te(2), two equivalent Te(3), and four equivalent Te(1) atoms to form a mixture of distorted edge, face, and corner-sharing PrTe8 hexagonal bipyramids. In the second Pr site, Pr(2) is bonded to two equivalent Te(1), two equivalent Te(3), and four equivalent Te(2) atoms to form a mixture of distorted edge, face, and corner-sharing PrTe8 hexagonal bipyramids. In the third Pr site, Pr(3) is bonded to two equivalent Te(2), three equivalent Te(1), and three equivalent Te(3) atoms to form a mixture of distorted edge, face, and corner-sharing PrTe8 hexagonal bipyramids. There are three inequivalent Te sites.
