The cover picture shows a sketch of a recently synthesized polycyclic molecule, 2,3,6,7,10,11,14,15,20,21,26,27‐dodecamethoxycentrohexaindane, bearing six 5,6‐dimethoxyindane units that are mutually fused along the three axes of the Cartesian space. This “Cartesian hexaveratrole” is strictly T d ‐symmetrical and topologically nonplanar because of its rigid centrohexaquinane core. It contains three truly linear 2,2′‐spirobiindane units that cross each other at right angles, and consequently, four [3.3.3]propellane and triquinacene moieties and even three [5.5.5.5]fenestrane units, all bearing the veratrole groupings at 90 and 180 ° to each other. Twelve‐fold centrohexaindanes can be envisaged to offer an access to three‐dimensional, supramolecular, highly porous networks in which their intrinsic orthogonality is perpetuated in all directions of the three‐space. Details are discussed in the article by M. Harig and D. Kuck on p. 1647 ff.
