Figure 3
Idealized hnb net-type describing the connectivity of the Si-atoms within a single silicate layer of Cs₄Ca[Si₈O₁₉]. The coordination sequences of the two different vertices (V1, V2) within this net-type are as follows: V1: 3-6-6-12-15-12-21-24-18-30 and V2: 3-4-8-12-11-18-19-18-28-26. The maximum topological symmetry of the hnb net is p3m1. The corresponding unit mesh is indicated.
