Pb2TeO5 crystallizes in the monoclinic C2/c space group. Pb(1) is bonded in a 5-coordinate geometry to two equivalent O(2) and three equivalent O(1) atoms. Te(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form corner-sharing TeO6 octahedra. The corner-sharing octahedral tilt angles are 42°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to three equivalent Pb(1) and one Te(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Pb(1) and one Te(1) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to two equivalent Te(1) atoms.
Pb2TeO5 crystallizes in the monoclinic C2/c space group. Pb(1) is bonded in a 5-coordinate geometry to two equivalent O(2) and three equivalent O(1) atoms. There is one shorter (2.39 Å) and one longer (2.53 Å) Pb(1)-O(2) bond length. There are a spread of Pb(1)-O(1) bond distances ranging from 2.39-2.65 Å. Te(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form corner-sharing TeO6 octahedra. The corner-sharing octahedral tilt angles are 42°.
