摘要

In the title compound, [Co(C5H4N3O2)2(H2O)2], the CoII atom is situated on a twofold rotation axis and is N,O-chelated by two 3-aminopyrazine-2-carboxylate anions and additionally bonded to the O atoms of two water molecules, leading to a slightly distorted octahedral coordination environment. The crystal packing is dominated by intermolecular O〞H...O, O〞H...N and N〞H...O hydrogen bonding involving the water molecules and amino groups as donors and carboxylate O atoms, as well as the non-coordinating heterocyclic N atoms as acceptors, resulting in a three-dimensional network. An intramolecular N〞H...O hydrogen bond is also observed.
