Entrapment of a Hexamer of Nitrobenzene Molecules between the Layers of (4,4)‐Coordination Networks Containing Intra‐β‐Sheet Hydrogen Bonds

Two exo ‐bidentate pyridyl ligands containing diamides as spacers were shown to form non‐interpenetrated 2D‐coordination networks of (4,4)‐geometry upon treatment with Cu(NO 3 ) 2 and NaSCN. The crystal structures reveal that both structures contain intralayer β‐sheet hydrogen bonds. In one of these structures nitrobenzene occupies 60 % of the crystal volume included between the coordination networks. The nitrobenzene molecules form a layer which has the hexameric C–H ··· O hydrogen bonded aggregate as a basic building block. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
