Full TextAbstract
The title compound, (C6H9N2)2[Co(C6H2N2O4)2(H2O)2]- 8H2O, was obtained by the reaction of CoCl26H2O with 1,4- pyrazine-2,3-dicarboxylic acid and 2-amino-6-methylpyridine in aqueous solution (molar ratio 1:2:2). The CoII ion is situated on an inversion centre and is coordinated by two O and two N atoms of two symmetry-related 1,4-pyrazine-2,3-dicarboxylate ligands and two water molecules and has a disorted octahedral coordination environment. The asymmetric unit also contains four water molecules. In the crystal, extensive intermolecular classical N—H O, O—H O and O—H N hydrogen bonds and – stacking interactions [centroid–centroid distance = 3.490 (1) A ° ] connect the various components, forming a three-dimensional network.
