PrTl2InTe4 crystallizes in the tetragonal I-42m space group. The structure consists of a PrTl2InTe4 framework. Pr(1) is bonded to four equivalent Te(1) atoms to form distorted PrTe4 tetrahedra that share edges with two equivalent In(1)Te4 tetrahedra. Tl(1) is bonded in a 4-coordinate geometry to four equivalent Te(1) atoms. In(1) is bonded to four equivalent Te(1) atoms to form InTe4 tetrahedra that share edges with two equivalent Pr(1)Te4 tetrahedra. Te(1) is bonded in a distorted L-shaped geometry to one Pr(1), two equivalent Tl(1), and one In(1) atom.
