Figure 2
A packing diagram for SrMn(SeO3)2 viewed down [100], in polyhedral representation. The SeO3 pyramids (light shading) are represented by SeO3E tetrahedra, where the dummy atom E, geometrically placed 1.0 Å from Se and indicated by a small sphere, represents the SeIV lone pair. Sr2+ cations are represented by spheres of arbitrary radii. |
