BaZrTiPbO6 crystallizes in the tetragonal P4mm space group. Ba(1) is bonded to four equivalent O(1), four equivalent O(2), and four equivalent O(4) atoms to form distorted BaO12 cuboctahedra that share corners with four equivalent Ba(1)O12 cuboctahedra, faces with four equivalent Ba(1)O12 cuboctahedra, and faces with four equivalent Ti(1)O6 octahedra. Zr(1) is bonded in a 6-coordinate geometry to one O(3), one O(4), and four equivalent O(1) atoms. Ti(1) is bonded to one O(3), one O(4), and four equivalent O(2) atoms to form TiO6 octahedra that share corners with four equivalent Ti(1)O6 octahedra and faces with four equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 9°. Pb(1) is bonded in a 4-coordinate geometry to four equivalent O(2) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Ba(1) and two equivalent Zr(1) atoms. In the second O site, O(2) is bonded in a distorted linear geometry to two equivalent Ba(1), two equivalent Ti(1), and two equivalent Pb(1) atoms. In the third O site, O(3) is bonded in a linear geometry to one Zr(1) and one Ti(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to four equivalent Ba(1), one Zr(1), and one Ti(1) atom.
