The corner-sharing octahedral tilt angles range from 1-9°. Pb(1) is bonded in a 6-coordinate geometry to one O(1), one O(5), two equivalent O(3), and two equivalent O(4) atoms. There are five inequivalent O sites. In the first O site, O(5) is bonded in a distorted T-shaped geometry to one Ba(1), three equivalent Fe(1), and one Pb(1) atom.
