The crystal structure described by HfTi(PbO3)2 is Pb(Zr_(1-x)Ti_x)O3-derived structured and crystallizes in the tetragonal I4mm space group. Hf(1) is bonded to one O(2), one O(3), and four equivalent O(1) atoms to form distorted HfO6 octahedra that share corners with six equivalent Ti(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-17°. Ti(1) is bonded to one O(2), one O(3), and four equivalent O(1) atoms to form distorted TiO6 octahedra that share corners with six equivalent Hf(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-17°. Pb(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Hf(1), one Ti(1), and two equivalent Pb(1) atoms. In the second O site, O(2) is bonded in a distorted linear geometry to one Hf(1) and one Ti(1) atom. In the third O site, O(3) is bonded in a distorted linear geometry to one Hf(1) and one Ti(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
