So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Mazalov, L. N.; Bausk, N. V.; Trubina, S. V.; Erenburg, S. B.; Fedotova, N. E.; Igumenov, I. K. researched the compound: Bis(2,2,6,6-tetramethyl-3,5-heptanedionato)nickel(II)( cas:14481-08-4 ).SDS of cas: 14481-08-4.They published the article 《Investigation of electronic and spatial structure of Ni(dpm)2 complex in solutions by X-ray absorption spectroscopy with use of synchrotron radiation》 about this compound( cas:14481-08-4 ) in Poverkhnost: Rentgenovskie, Sinkhrotronnye i Neitronnye Issledovaniya. Keywords: electronic structure nickel dipivaloylmethanato complex x ray absorption XANES; adduct nickel dipivaloylmethanate water pyridine ethanol XANES. We’ll tell you more about this compound (cas:14481-08-4).
Studying XANES (X-ray Absorption Near Edge Structure) K-spectra of nickel in the bis(dipivaloylmethanato)nickel as well as in a series of its solutions and adducts was carried out. X-ray spectra were obtained at the station of the Synchrotron Radiation Center in the Institute of Nuclear Physics, Siberian Branch Russian Academy of Sciences. It was shown, that the main absorption maximum of investigated compounds had Rydberg’s character. The fine structure of the main maximum was used to establish a structure of the nearest environment of the metal atom of the complex in solutions and adducts. The involvement of the highest unoccupied metal AOs in the chem. bond was examined
