Figure 1 Arrangement of anions around each Ba atom. The displacement ellipsoids are given at 50% probability. The symmetry codes are: (i) −x + 1, −y, −z; (ii) −x + 1, −y + 1, −z; (iii) −x + , −y + 1, z + ; (iv) −x + , −y, z + ; (v) x, y + 1, z; (vi) −x + , −y, z − ; (vii) −x + 2, −y, −z; (viii) −x + , −y + 1, z − ; (ix) x, y − 1, z. |
