چکیده
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.

The title compound, [Na(C(23)H(28)N(17)OS(2))(CH(3)OH)(C(6)H(5)OH)]·4C(6)H(5)OH, is a five-coordinate Na(I) complex. The Na(+) cation is bound to three N atoms of the triazinide ligand, two from each pyrazole ring and one from the central deprotonated triazine ring system. O atoms from a methanol and a phenol mol-ecule complete the five-coordinate NaN(3)O(2) coordination environment. The asymme...
