The infrared spectra of coordinated perchlorates

The infrared spectra of a series of copper(II) perchlorate complexes have been examined in the light of their known solid state structures and the spectroscopic predictions based on group theory. The spectra of complexes containing coordinated perchlorate are readily distinguished from those containing uncoordinated perchlorate by the presence of a second band near 650 cm−1. The mode of coordination of the perchlorate ion to a complex cation, however, is difficult to determine on the basis of infrared spectroscopy alone.
