Hasegawa, Miki published the artcileElectronic structure of Cu(II) complexes with N,N’-disalicylidene-1,2-cyclohexanediamine and N,N’-disalicylidenetrimethylenediamine, Name: Propane-1,3-diamine dihydrochloride, the publication is Monatshefte fuer Chemie (2002), 133(3), 285-298, database is CAplus.
The electronic absorption and x-ray photoelectron spectra of N,N’-disalicylidenetrimethylenediaminatocopper(II) ([Cu(saltn)]) and N,N’-disalicylidene-trans-1,2-cyclohexanediaminatocopper(II) ([Cu(salchx)]) were measured. From these results and from informations derived from MO calculations the electronic structure of the complexes was clarified. Each electronic absorption band which can be assigned to the ¦Ð¦Ð* or ML/LMCT transition of [Cu(saltn)] or [Cu(salchx)] observed in the wavelength region of 450-200 nm appears at the almost same frequency as the corresponding band of N,N’-disalicylideneethylenediaminatocopper(II) ([Cu(salen)]) in solution The LLCT bands (the intramol. CT band between two ¦Ð-electronic systems separated by saturated hydrocarbon chains such as -(CH2)n–) also appear at nearly the same positions (?245 nm) for [Cu(salchx)], [Cu(saltn)], and [Cu(salen)]. The locations of the dd transition and the intensity of the ML/LMCT transition of [Cu(saltn)] are significantly different from those of [Cu(salen)] and [Cu(salchx)]. These differences may arise from the strengths of the interaction between metal and ligand.
