A comment on the crystal structure and electronic properties of bis(2,9-dimethyl-1,10-phenanthroline)nitratocopper(II) trichloroacetate trichloroacetic acid

Abstract

A re-examination of the electronic properties and structure of [Cu(dmphen)₂(O₂NO)][CCl₃CO₂]·CCl₃CO₂H (dmphen = 2,9-dimethyl-1,10-phenanthroline) suggests that it is best described as a distorted squarepyramidal cis octahedral CuN₄O₂ chromophore (4 + 1 + 1*) as suggested by the electronic reflectance spectrum, but involving a novel sense of distortion.
