A new supramolecular compound of Fe(III) atom was synthesized and characterized by using elemental analysis, FTIR spectroscopy, UV-vis, and single crystal X-ray diffraction method. The chemical formula and space group of the resulting compound is (2-apymH)[Fe(pydc)2].2H2O (1) ( pydc = 2,6-pyridinedicarboxylate, 2-apym = 2-aminopyrimidine) and P21/c where the final R value is 0.0287 for 14861 reflections collected. The [Fe(pydc)2]– anions and the (2-apymH)+ moiety form a three–dimensional solid state structure by a variety of noncovalent interactions such as ion pairing and hydrogen bonds interactions and one can conclude it as host-guest system. On the basis of crystallographic data, it can be seen that Fe(III) atom is six-coordinated by two (pydc)2– groups. With respecting to bond lengths and angles, it is observed that coordination sphere around Fe(III) atom is a distorted octahedral.
