Twenty two new complexes of some tervalent metals (aluminum, chromium, iron, and lanthanides) with nitrozohydroxylamine N-alkyl(benzyl) derivatives · nH 2 O, (m = 1-5) were synthesized and isolated in a crystalline state. The crystal and molecular structures of the iron(III) complex with N-(2-fluorobenzyl)-N-nitrozohydroxylamine were determined by X-ray diffraction. An octahedral coordination of the central ion and a bidentate chelating coordination of the organic ligand were established. The spectral criteria of coordination of nitrozohydroxylamine alkyl(benzyl) derivatives were determined, and the complexation processes in solutions were studied.The compounds containing N-nitrozohydroxylamine moieties are good chelating reagents able of forming stable metal complexes with metals of various types. They are widely used in chemistry as analytical reagents for the extraction of many metals [1][2][3][4][5][6][7][8][9][10][11][12][13][14] and their spectrophotometric analysis [15], and as precursors for the synthesis of nanoparticles of metal oxides [16][17][18][19][20].

“…When passing to the coordination compounds, the bands of azo and azoxy groups sustain shift towards higher and lower frequencies (Table 4), respectively. This evolution in the IR spectra corresponds to the participation of the azoxy groups of organic molecules in coordination to metals and was earlier studied in detail for the diazeniumdiolate complexes used as an example [20][21][22][23].…”

CCDC no.: 1447423The crystal structure is shown in the gure. Tables 1-3 contain details of the measurement method and a list of the atoms including atomic coordinates and displacement parameters. Source of materialUnder atmospheric conditions, NbCl5 (0.27 g, 1 mmol) was dissolved in acetonitrile (10 mL), and treated with tetraethylammonium chloride (0.165 g, 1 mmol). The mixture was re uxed overnight at 90-100°C and the solvent was removed under vacuum. (0.2604 g, 1.68 mmol) at room temperature. The resulting mixture was stirred for 4 h, and then the volatile material was removed in vacuo. The resulting residue was washed with diethyl ether (2 × 10 mL), giving a grey solid and the solution was left to stand at 255 K for a few days after which red crystals were obtained. Atom Site Experimental detailsThe H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms, with C-H = 0.98 Å and Uiso(H) = 1.2Ueq(C), respectively. The highest peak (2.37 e. Å −3 ) is located 1.07 Å from O4 and the deepest hole (−0.65 e. Å −3 ) is situated 0.69 Å from Nb1. DiscussionThe ammonium salt of N-nitroso-N-phenylhydroxylamine, is a well-known analytical reagent (cupferron) and it was very popular especially for analytical separations [1, 2]. The chelate-forming derivatives of this ligand is known to form stable complexes with various metals, but only few of them have been structurally characterized [3][4][5][6][7][8][9][10][11][12]. Also some cupferrates were investigated in our group [13][14][15][16][17][18]. This study forms part of ongoing research to investigate the mechanism of the reactions of O,O′-and N,O-bidentate ligands with transition metals used in nuclear industry, such as Hf, Zr, Nb,.In the title structure the Nb atom is heptacoordinated by six oxygen atoms, of three bidentate cupferron ligands and an oxido group. The cupferrate ligand forms a ve-membered ring with a small bite angle (see the gure). The Nb-O distances are between 1.7107 (5) and 2.2267 (7) Å, and the O-Nb-O angles vary between 68.36(2)°and 158.51(2)°. All the bond distances and angles are similar to other relevant niobium(V) structures [27,28].Acknowledgements: Financial assistance from the faculty
