Geometric relation between the octa­hedral tilt about c and the inter­atomic bonds of disordered Tb atoms. The seven bonds around the a site populated by most Tb atoms are drawn with thick lines. The five short bonds and additional two long bonds around the b site populated by trace amounts of Tb atoms are drawn with thin and dashed lines, respectively. [Symmetry codes: (i) [x+{1\over2}, -y+{1\over2}, z-{1\over2}]; (ii) [x+{1\over2}], -y+1, -z; (iii) [x+{1\over2}, -y, -z].]
