Easy obtainment of three-dimensional coordination polymer of zinc 1,2,4,5-benzenetetracarboxylate with para-amino-pyridinium cations

Within a wide study on coordination polymers coming from 1,2,4,5-benzenetetracarboxylate combined with arom. amines and first row transition metal ions, we isolated and characterized a peculiar tridimensional coordination polymer made by an anionic mesoporous scaffold of Zn(II)-benzeneteracarboxylate whose charge is balanced by included p-aminopyridinium cations stacked up along two quasi-perpendicular crystallog. directions. The particular features of the solid state structure, easily obtained in std. conditions, prompts a wider research of possible related derivs.
