Bottom Line: In the title compound, [Co(C(5)H(4)N(3)O(2))(2)(H(2)O)(2)], the Co(II) atom is situated on a twofold rotation axis and is N,O-chelated by two 3-amino-pyrazine-2-carboxyl-ate anions and additionally bonded to the O atoms of two water mol-ecules, leading to a slightly distorted octa-hedral coordination environment.The crystal packing is dominated by inter-molecular O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonding involving the water mol-ecules and amino groups as donors and carboxyl-ate O atoms, as well as the non-coordinating heterocyclic N atoms as acceptors, resulting in a three-dimensional network.An intra-molecular N-H⋯O hydrogen bond is also observed.
