3 Nets derived from the net of the primitive cubic lattice (pcu). Deconstructing the Crystal Structures of Metal–Organic Frameworks and Related Materials into Their Underlying Nets Michael O’KeeffeMichael O’Keeffe *†‡ and Omar M. Yaghi *‡§*Omar M. Yaghi* Chem. Rev., 2012, 112 (2), pp 675–702 DOI: 10.1021/cr200205j

7 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.
