Supramolecular architecture from a sodium coordination polymer with a eD net containing 3-aminopyrazine-2-carboxylic acid (APZC):: Synthesis, characterization and crystal structure of [Na2(APZC)2(μ-H2O)2(μ3-H2O)]n

The synthesis and spectroscopic properties of a Na+ complex with ligand 3-aminopyrazine-2-carboxylic acid were described. The resulting complex was characterized by elemental analysis, IR, UV-Vis, NMR spectroscopy and single crystal X-ray diffraction method. The title compound crystallizes in the triclinic system with space group P (1) over bar. The crystalline structure of this compound consists of supramolecular architectures involving strong intramolecular N-H center dot center dot center dot O in pyrazine molecules and intermolecular O-H center dot center dot center dot N, O-H center dot center dot center dot O, and N-H center dot center dot center dot N hydrogen bonds between substituted pyrazine and water molecules.
