Figure 2
(a) Arrangement of NaOx polyhedra into edge-sharing clusters comprised of two Na1O6 octa­hedra and two Na2O5 square pyramids; (b) Arrangement of the clusters shown in (a) by corner sharing to form `slabs' parallel (010). Ellipsoids are drawn at the 50% probability level. [Symmetry codes: (i) 1 − x, 1 − y, 1 − z; (ii) [{1\over 2}] + x, [{3\over 2}] − y, 1 − z; (iii) −[{1\over 2}] + x, [{3\over 2}] − y, 1 − z; (iv) [{1\over 2}] − x, −[{1\over 2}] + y, z; (v) [{1\over 2}] + x, y, [{3\over 2}] − z; (vi) [{1\over 2}] − x, 1 − y, [{1\over 2}] + z; (vii) [{3\over 2}] − x, −[{1\over 2}] + y, z.]
