Figure 4
Crystal structures of x-C₂S and α-C₂SH, viewed along (a) the c axis of x-C₂S and (b) the a axis of α-C₂SH. Tunnels with pentagonal-shaped sections run perpendicular to the diagrams. Orange spheres in x-C₂S represent Ca(3) and Ca(4) atoms, belonging to the group of large polyhedra (G_L) (§5.3.2

). Blue spheres in α-C₂SH represent hydroxyls. The other spheres represent respective atoms as in Fig. 3
