Beauty is in the I of the beholder : Metal‐ion coordination and I⋅⋅⋅I halogen bonding direct the self‐assembly of achiral starting materials (a calix[4]arene tetraamide, BaI 2 ⋅2 H 2 O, and 1,8‐diiodoperfluorooctane) into a homochiral supramolecular complex containing double helices (see structure; Ba light purple, I purple, F green, O red, N blue, C gray; one double helix in red and yellow).
