Fifteen components build a supermolecule , comprised of two water molecules binding [18]crown‐6 and this is itself enclosed by six saddle‐shaped [Ni(tmtaa)] 2 macrocycles (see picture). The supermolecule interlocks into a two‐dimensional layer. An analogous, metal‐free supermolecule affords a layered structure consisting of (H 2 TMTAA) 2 dimers separated by layers of [18]crown‐6.
