7,15‐Dihydroxy[2.2](2,6)pyridinophane: Synthesis via Organoselenium Compounds and Aggregation by Hydrogen Bonds * 7,15‐Dihydroxy[2.2](2,6)pyridinophane ( 5 ) was prepared by using dimethoxy‐diselena[3.3]pyridinophane 3 as a precursor. The X‐ray structural analyses of both phanes (5 x 2 HI x 2 DMSO and 3 ), show the extremely syn ‐shaped [3.3]phane 3 and the [2.2]phane 5 with antagonistically hydrogen‐bonded solvent molecules.
