In the past few years, supramolecular complexes have attracted extensive attention because they possess potential properties in catalysis, magnetic behavior, optical material, and adsorption. A various number of complexes containing transitional metal ions and bridging multifunctional organic ligands with N- and O-donors have been reported. In particular, N-containing polycarboxylates such as pyrazine- and pyridine-carboxylates are efficient building blocks in constructing novel coordination compound. Herein, a new supramolecular coordination compound of zincII- based pyrazine-2,3-dicarboxylic acid (pzdcH2) with 2-amino-4-methyl pyridine (ampy), (ampyH)[Zn(pzdc)2.2H2O].6H2O, has been reported for the first time. The title compound has been characterized by means of elemental and thermal analyses, IR spectroscopy and single crystal X-ray diffraction technique. In the title compound pzdcH2 acts as a bidentate ligand through oxygen atom of carboxylate group and N atom of pyrazine aromatic ring. Different hydrogen bond causes the title compound to form three-dimentional framework. The combinations of hydrogen-bonding and metal-coordination motifs have created a interesting supramolecular motif
