Abstract
In the crystal structure of the mononuclear title compound, (C5H8N3)2[Co(C6H2N2O4)2(H2O)2]6H2O or (ampymH)2[Co- (pyzdc)2(H2O)2]6H2O (ampym = 2-amino-4-methyl pyrimidine, pyzdcH2 = pyrazine-2,3-dicarboxylic acid), the CoII ion is hexacoordinated by two (pyzdc)2 groups in the equatorial plane and two water molecules in axial positions, giving an N2CoO4 bound set. The (pyzdc)2 anion acts as a bidentate ligand through one carboxylate group O atom and pyrazine ring N atom. There are diverse N—H O and O—H O and O—H N hydrogen-bonding interactions, which lead to the formation of a three-dimensional supramolecular architecture. Off-set or slipped – stacking interactions are also observed between adjacent pyrimidine rings with face-to-face distances of 3.6337 (9) A ˚ .
