Two 3D supramolecular architectures from zinc hydrogen aconitate 1D polymers

The reaction of Zn(NO3)2 · 3(H2O) with trans-aconitic acid, in presence of chelating Lewis bases, leads to the formation of the 1D polymers [Zn(N–N)(LH)] · nH2O, where LH3 = trans-aconitic acid, 1 : N–N = 1,10-phenanthroline (phen), n = 1, 2 : N–N = 2,2′-bipyridine (bpy), n = 2. 3D supramolecular assemblies are constructed through H-bonding and stacking interactions.
