Application of 14481-08-4. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: Bis(2,2,6,6-tetramethyl-3,5-heptanedionato)nickel(II), is researched, Molecular C22H38NiO4, CAS is 14481-08-4, about Application of the angular overlap model to the interpretation of the electronic spectra of copper(II) and nickel(II) acetylacetonate complexes. Author is Hitchman, M. A..
σ- And π-bonding parameters were calculated by the angular overlap model for CuL2 nLH = MeCOCH2COMe, MeCOCH2COPh, MeCOCHPnCOMe) and Ni(Me3CCOCHCOCMe3) (I). The results suggested the orbital sequence dxy ≫ dz2 > dx2-y2 > dxz ∼ dyz for the Cu complexes but dxy ≫ dx2-y2 > dz2 > dxz ∼ dyzfor I due to stronger metal-ligand interaction. The parameters estimated for I were used to predict d-orbital splittings for [NiL2]3, NiL2.2H2O, and NiL2.py2 (LH = MeCOCH2COMe).
