摘要

In the title complex, [Ba(C10H12N5O6)(2)(H2O)(6)](n) the Ba atom is nine-coordinated by six water ligands and three carboxylate O atoms. The Ba2+ cations and the anionic glutamate ligands form coordination polymer chains, and these chains are linked by pairs of N-H••• O hydrogen bonds and pairs of O-H••• O hydrogen bonds to form a continuous three-dimensional framework of cations and anions, which is reinforced by hydrogen bonds involving the water molecules.
