Figure 6
Schematic drawing of the building scheme used to construct the zeolite topologies in the family of dense double-crankshaft topologies. Each arrow represents a double-crankshaft chain, as seen in projection along the chain direction, and the direction of the arrow indicates the relative rotational orientation. There is only one physically meaningful solution to the connectivity between double-crankshaft chains for each of the schematic drawings, which results in the final topology. Colours have been applied for visual emphasis of symmetry.
