Three novel bis-and trinitroso compounds derived from 1,3,5trihydrohybenzene (phloroglucinol), 2,4,6-trihydroxy benzoic acid, and 2,4,6-trihydroxyacetophenone were isolated, their spectral characteristics, ionization constants and thermodynamic parameters of dissociation process were calculated. The comparison of the stability of nitroso and hydroxylimino tautomeric forms was performed by DFT calculations. Nine complexes of the ligands with Cu(II), Cd(II), and Fe(III), were isolated and studied by elemental analyses, X Ray analysis and spectroscopic methods. According to the crystal structure determination, the Cd complex with the phloroglucinol based ligand exists in the form of a binuclear compound. The QTAIM Bader topological analysis indicated that the binuclearity of the Cd complex is due to strong interatomic interactions between Cd atoms with bifurcate carbonyl groups of the ligands and strong H-interactions involving coordinated and lattice water molecules. The equilibria of reactions of complex formation of the organic species with Cu 2 + , Cd 2 + , and Fe 3 + was studied by spectrophotometric titration, and the composition of the complexes in solutions and their stability constants were calculated. The ability of the isolated organics to remove metal cations from the aqueous solutions was studied in the pH interval 3-6 and the rate of Cu 2 + removal from aqueous solutions was found close to 100 %.

“…As a result, a three-dimensional network is formed. The described structure is in accordance with the other known structures of complexes of 1,2-benzo(naphto) quinone -1-oximes with the alkaline (Charalambous et al, 1993(Charalambous et al, ,1995Adatia et al, 1996) and transition metals (Basu and Chakravorty, 1992;Charalambous et al, 1996;McPartlin, 1973) where the formation of monomeric complexes with the bidentate chelating coordination mode of the ligands was observed. The only one difference is in the nature of the hydroxyimino group which is not ionized in the structure reported here.…”

In the title compound, [Ba(C7H5N2O5)2(H2O)6]·4H2O, the Ba2+ cation lies on a twofold rotation axis and is ten-coordinated by two 3,5-bis(hydroxyimino)-1-methyl-2,4,6-trioxocyclohexanide oxo O atoms [Ba—O = 2.8715 (17) Å], two hydroxyimino N atoms [Ba—N = 3.036 (2) Å], and six water molecules [Ba—O = 2.847 (2), 2.848 (2), and 2.880 (2) Å]. The 3,5-bis(hydroxyimino)-1-methyl-2,4,6-trioxocyclohexanide monoanions act in a bidentate chelating manner, coordinating through an N atom of the non-deprotonated hydroxyimino group and an O atom of the neighboring oxo group. Two lattice water molecules are located in the cavities of the framework and are involved in hydrogen bonding to O atoms of one of the coordinating water molecules and the O atom of a keto group of the ligand. As a result, a three-dimensional network is formed.
