The crystal structure described by Cu3PbTeO7 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to one O(1), one O(2), one O(4), one O(5), and two equivalent O(3) atoms to form distorted CuO6 octahedra that share  a cornercorner with one Te(1)O6 octahedra, corners with two equivalent Cu(1)O6 octahedra,  a cornercorner with one Pb(1)O5 square pyramid, edges with two equivalent Te(1)O6 octahedra, edges with three equivalent Cu(1)O6 octahedra, and  an edgeedge with one Pb(1)O5 square pyramid. The corner-sharing octahedral tilt angles range from 19-59°. In the second Cu site, Cu(2) is bonded in a distorted square co-planar geometry to one O(1), one O(2), and two equivalent O(4) atoms. Pb(1) is bonded to one O(2), two equivalent O(4), and two equivalent O(5) atoms to form distorted PbO5 square pyramids that share corners with two equivalent Cu(1)O6 octahedra, corners with two equivalent Te(1)O6 octahedra,  an edgeedge with one Te(1)O6 octahedra, and edges with two equivalent Cu(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 52-58°. Te(1) is bonded to one O(1), one O(3), two equivalent O(4), and two equivalent O(5) atoms to form TeO6 octahedra that share corners with two equivalent Cu(1)O6 octahedra, corners with two equivalent Pb(1)O5 square pyramids, edges with four equivalent Cu(1)O6 octahedra, and  an edgeedge with one Pb(1)O5 square pyramid. The corner-sharing octahedral tilt angles are 59°. There are five inequivalent O sites. In the first O site, O(4) is bonded in a 4-coordinate geometry to one Cu(1), one Cu(2), one Pb(1), and one Te(1) atom. In the second O site, O(5) is bonded in a distorted trigonal planar geometry to one Cu(1), one Pb(1), and one Te(1) atom. In the third O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to one Cu(2), two equivalent Cu(1), and one Te(1) atom. In the fourth O site, O(2) is bonded in a distorted tetrahedral geometry to one Cu(2), two equivalent Cu(1), and one Pb(1) atom. In the fifth O site, O(3) is bonded in a 5-coordinate geometry to four equivalent Cu(1) and one Te(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
