The effects of mono-valent cations, Li⁺, K⁺, Rb⁺, Cs⁺ and NH₄⁺, on ²³Na NMR were investigated. It was found that the chemical shifts for Na⁺ signal shifted downfield with the increase in the relative amounts of monovalent cations. It was suggested that mono-valent cations had competition coordination with Na⁺ for Dy (PPP) ₂^7-.
