Abstract
The Co atom, the pyrazine heterocycle and the phthalate dianion are in special positions in the crystal structure of the title compound, [Co(C4H4N2)(H2O)(4)](C8H4O4); the Co atom and the N-heterocycle are located on sites of mmm symmetry, whereas the dianion is disordered over a 2mm site. The four water ligands constitute a square plane surrounding the Co atom, and the other two coordination sites are occupied by the N atoms of two different N-heterocycles. The cationic entity propagates as a linear mu-pyrazine-bridged chain that runs along the a axis of the orthorhombic unit cell. The dianion interacts with the Co atom through hydrogen bonds.
