Intergrown nets
Figure 4: Catenation of rings in nets intergrown with their dual structures. The nets are shown augmented with triangles at the three-coordinated vertices and octahedra at the six-coordinated vertices. a, A pair of identical rings in the self-dual pyr net of MOF-150 (ref. 11). b, A six-membered ring of the qom net (red) of MOF-177 catenated with a ring of the dual net (blue). A pair of three-coordinated vertices are directly linked, as are pairs of six-coordinated vertices.
