| Popis: | 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•••N and O—H•••O contacts, which lead to the formation of a three-dimensional supramolecular architecture.DOI: http://dx.doi.org/10.4314/bcse.v26i1.15 |
