| Summary: | The asymmetric unit of the title compound, {(C5H7N2)2[Ni(C10H2O8)(H2O)4]·2H2O}n, contains an NiII atom, two water molecules of coordination, one half of a benzene-1,2,4,5-tetracarboxylate (btec) anionic ligand, one 4-aminopyridinium cation (papy) and an uncoordinated water molecule. The metal center lies on an inversion center and adopts an octahedral geometry with the carboxylate groups tilted out of the mean plane formed by the btec. In the crystal, molecules are linked into one-dimensional coordination polymers running along the ac diagonal. The crystal structure is consolidated by N—H...O and O—H...O hydrogen bonds. |
