Bis(2-amino-6-methyl-pyridinium) trans-diaqua-bis-(pyrazine-2,3-dicarboxyl-ato)cobaltate(II) octa-hydrate.


ABSTRACT: The title compound, (C(6)H(9)N(2))(2)[Co(C(6)H(2)N(2)O(4))(2)(H(2)O)(2)]·8H(2)O, was obtained by the reaction of CoCl(2)·6H(2)O with 1,4-pyrazine-2,3-dicarb-oxy-lic acid and 2-amino-6-methyl-pyridine in aqueous solution (molar ratio 1:2:2). The Co(II) 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-dicarboxyl-ate ligands and two water mol-ecules and has a disorted octa-hedral coordination environment. The asymmetric unit also contains four water mol-ecules. In the crystal, extensive inter-molecular classical N-H?O, O-H?O and O-H?N hydrogen bonds and ?-? stacking inter-actions [centroid-centroid distance = 3.490?(1)?Å] connect the various components, forming a three-dimensional network.
