ZrTi(PbO3)2 crystallizes in the trigonal R3m space group. Zr(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form ZrO6 octahedra that share corners with six equivalent Ti(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 12-13°. Ti(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form TiO6 octahedra that share corners with six equivalent Zr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 12-13°. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 3-coordinate geometry to three equivalent O(1) atoms. In the second Pb site, Pb(2) is bonded in a 3-coordinate geometry to three equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Zr(1), one Ti(1), and one Pb(1) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Zr(1), one Ti(1), and one Pb(2) atom.
