A new complex of Zinc(II) and guanidinium pyridine–2,6–dicarboxylate proton transfer compound, (GnH)₂ (pydc), was synthesized and characterized using IR, ¹H NMR and ¹³C NMR spectroscopy and single crystal X–ray diffraction. The chemical formula and space group of the resulting complex is (GnH)[Zn(pydc)(pydcH)] ^. (pydcH₂) ^. 4H₂O, P-1 where the final R value is 0.0310 for 13287 reflections collected. The [Zn(pydc)(pydcH)]^– anions and the (GnH)⁺ counter-cations form a three-dimensional solid-state structure by a variety of noncovalent interactions such as ion pairing, hydrogen bonding and π–π stacking which are going to be discussed.
