Figure 2
(a) A view of the one-dimensional centrosymmetric double-chain structure of (I)[link], based on 32-membered metallated macrocycles, showing the nitrate anions connected through multiple N—H⋯O hydrogen-bond inter­actions (dashed lines). (b) A space-filling view of the double-chain structure, consisting of two chiral chains individually constructed of S and R conformers bridging the metal centres. The encapsulated nitrate anions have been omitted for clarity.
