The supramolecular network of the complex having the formula [Cu(nicot) 2 · 2NH 3 · 2H 2 O] · 6H 2 O 1 has been synthesized by transmetallation of the Zn–nicotinate complex by Cu II ions and its crystallization in an ionic liquid. The supramolecular network of 1 shows unique H‐bonding in the sense that it not only participates in the formation of nanoporous 2D chains but also forms cyclic hexameric water cluster that adopt an ice‐like chair conformation, which together with octanuclear H‐bonded rings extend the network into a 3D open framework. X‐ray structural analysis, FTIR, thermal analysis, EPR and magnetic properties have been used to characterize this compound. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
