Pr2TeO6 crystallizes in the orthorhombic P2_12_12_1 space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded to one O(4), one O(5), one O(6), two equivalent O(2), and two equivalent O(3) atoms to form distorted PrO7 hexagonal pyramids that share corners with three equivalent Te(1)O6 octahedra, edges with two equivalent Pr(1)O7 hexagonal pyramids, and edges with two equivalent Te(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 34-43°. In the second Pr site, Pr(2) is bonded in a 7-coordinate geometry to one O(2), one O(3), one O(4), one O(5), one O(6), and two equivalent O(1) atoms. Te(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form TeO6 octahedra that share corners with three equivalent Pr(1)O7 hexagonal pyramids and edges with two equivalent Pr(1)O7 hexagonal pyramids. There are six inequivalent O sites. In the first O site, O(6) is bonded in a 3-coordinate geometry to one Pr(1), one Pr(2), and one Te(1) atom. In the second O site, O(1) is bonded in a trigonal non-coplanar geometry to two equivalent Pr(2) and one Te(1) atom. In the third O site, O(2) is bonded in a 4-coordinate geometry to one Pr(2), two equivalent Pr(1), and one Te(1) atom. In the fourth O site, O(3) is bonded to one Pr(2), two equivalent Pr(1), and one Te(1) atom to form distorted corner-sharing OPr3Te tetrahedra.

In the sixth O site, O(5) is bonded in a 3-coordinate geometry to one Pr(1), one Pr(2), and one Te(1) atom.
