Figure 1
(a) [Si4O12] vierer single ring and (b) insular [SiO4] tetra­hedron in the crystal structure of (K1.5Na0.5)Ca3Si3O10. The projection is parallel to [100]. Oxygen and silicon atoms are shown in red and blue, respectively. Displacement ellipsoids are drawn at the 70% probability level. [Symmetry codes: (i) x, y − 1, z; (ii) 1 − x, −y, −z; (iii) 1 − x, 1 − y, −z; (iv) 1 + x, y, z; (v) 2 − x, 1 − y, 1 − z]
