Unraveling the Coordination Geometry of Copper(II) Ions in Aqueous Solution through Absorption Intensity

Strong colors: The solvation structure of copper(II) ions in water can be determined by optical absorption spectroscopy. Focus is placed on the absorption intensity (green: Cs2Cu(SO4)2⋅6 H2O, black: CuSO4⋅5 H2O, red: Cu2+ in aqueous solution, and blue: Cu2+ in glass). A dynamical model based on a Ja...

Zusammenfassung:	Strong colors: The solvation structure of copper(II) ions in water can be determined by optical absorption spectroscopy. Focus is placed on the absorption intensity (green: Cs2Cu(SO4)2⋅6 H2O, black: CuSO4⋅5 H2O, red: Cu2+ in aqueous solution, and blue: Cu2+ in glass). A dynamical model based on a Jahn–Teller‐distorted complex describes the coordination of copper(II) ions in hydrate crystals and aqueous solution.
