New germanium(IV) complexes with N-[X-benzoyl]hydrazones of salicylaldehyde (X-H2L, where X = 2-, 3-, and 4-NO2; H2L = C6H4–CO–NH–NCH–C6H4OH) with the compositions [Ge(2-NO2–L)2], [Ge(3-NO2–L)2], and [Ge(4-NO2–L)2] were synthesized. The data of IR, UV, and 1H, 13C NMR spectroscopy showed that the complexes had an octahedral structure and ligand coordination through the nitrogen atom of the azomethine group and two oxygen atoms of the doubly deprotonated form of the ligand. The thermal stability of the complexes was studied. The specific features of the mass spectrometric behavior of the substances in the gas phase under electron impact were considered. 相似文献

The results of systematic investigations into complexation between germanium tetrachloride and nitrogen- and oxygen-containing organic molecules in various organic solvents and water were generalized. Primary attention was given to the effects of the solvent nature and functional peculiarities of ligand systems on the composition, structure, and physicochemical properties of the germanium complexes obtained. 相似文献

The reactions of SnCl4 with picolinoylhydrazones of 2-hydroxybenz-(2-hydroxynaphth)aldehydes (H2Ps, H2Pnf) in CH3OH gave non-electrolyte complexes [SnCl3(Ps · H)] · CH3OH (I) and [SnCl3(Pnf · H)] · CH3OH (II). The imide form of the ligand coordinated to Sn(IV) through the azomethine nitrogen atom and oxyazine and oxy oxygen atoms was proved by UV/Vis, IR, and 1H NMR spectroscopy. The negative charge on the coordination unit thus arising is counterbalanced by the positive charge caused by the protonation of ligands at the pyridine nitrogen atom of the heterocycle. It was shown that dehydrochlorination of the complexes affords tin-containing species, which correlates with the presence of the corresponding peaks [SnCl2(Ps)]+ and [SnCl2(Pnf)]+ in their mass spectra. The molecular and crystal structures of complexes I and II were determined by X-ray diffraction. 相似文献

The reactions of GeCl4 with 2-hydroxynaphthaldehyde pyridinoylhydrazones (H2L) in methanol give complexes [Ge(L · HCl)2] · nH2O. The data of mass spectrometry, thermogravimetry, and IR and 1H NMR spectroscopy indicate that the ligand molecules are protonated at the pyridine nitrogen atom with hydrogen chloride and coordinated to germanium in the tridentate mode through the azomethine nitrogen atom and the oxyazine and oxy group oxygen atoms. The structure of the complex with isonicotinoylhydrazone (H2Inf), [Ge(Inf · HCl)2] · 5H2O has been determined by X-ray diffraction 相似文献
