Bis(2-amino-6-methyl­pyridinium) trans-diaqua­bis­(pyrazine-2,3-dicarboxyl­ato)cobaltate(II) octa­hydrate

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-dicarb­oxy­lic acid and 2-amino-6-methyl­pyridine in aqueous solution (molar ratio 1:2:2). The Co(II) ion is situated on an inversion centre and is co...

description 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-dicarb­oxy­lic acid and 2-amino-6-methyl­pyridine 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-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 π–π stacking inter­actions [centroid–centroid distance = 3.490 (1) Å] connect the various components, forming a three-dimensional network.
