Abstract
A mixed ligand complex, copper-(adeninato) (diethylenetriamine) monohydrate, was prepared and the coordination site of the compound was suggested from infrared spectroscopic analysis. Assignments of infrared bands of this compound are discussed in some detail. Electron paramagnetic resonance (EPR) spectra of this compound were recorded at room temperature and the EPR spectral line shape and g-values were compared with those of other mixed ligand complexes containing the adenine ligand. It was assumed that the coordination sphere of Cu2+ was a square-based pyramidal and the nitrogen atom N9 of adenine monoanion coordinated with Cu2+.
