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

Abstract

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(NO3)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
