Figure 1
The asymmetric unit of (I) expanded to include the full Zr and As coordination polyhedra showing 50% displacement ellipsoids. Only one disorder component about As2 is shown. Symmetry codes: (i) 1 − x, 1 − y, −z; (ii) y, 1 − x − y, −z; (iii) 1 − y, 1 + x − y, z; (iv) − x, − x + y, − z; (v) x − y, x, −z; (vi) y − x, 1 − x, z. |
