The compound described by 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. is represented by the Crystallographic Information File (CIF) [CIF]
