| Description | The determined structure of the title compound C24H20Ni2N8O20 consists of the mononuclear trans-[Ni(pyzdc)(2)(H2O)(2)], (pyzdc = pyrazine-2,3- dicarboxylate). The Ni(II) atom is hexa-coordinated by two (pyzdcH)(-) groups and two water molecules. The coordinated water molecules are in trans-diaxial positions and the (pyzdcH)(-) anion acts as a bidentate ligand through an O atom of the carboxylate group and the N atom of the pyrazine ring. There are diverse hydrogen bonding interactions such as O-H center dot center dot center dot N and O-H center dot center dot center dot O contacts, which lead to the formation of a three-dimensional supramolecular architecture. |
