摘要: Energy-dispersive X-ray absorption spectroscopy was applied, aimed at solving the problem of structure and stability a copper(II) lactate complex in alkaline solution, used as precursor for electrodeposition Cu2O. The application multiple scattering calculations to simulation near-edge part spectra allowed an accurate resolution structure: cation is surrounded by four ions distorted tetrahedral environment, with anions acting monodentate ligands. This results atomic arrangement where copper oxygen atoms located quite short distance (ca. 1.87 A) far apart 3.1–3.2 A). finally found be stable wide range applied potentials.
