Abstract

Replacement of the heteroatom from Si to Ge has a strong influence on the luminescence properties of a series of hybrid, sandwich-type K₅[Ln(α-GeW₁₁O₃₉)(C₂₀H₂₂Br₂N₂O₄)]·14H₂O (1_Ge-Ln, Ln = Sm to Lu) anions. Interestingly, the Gd and Yb derivatives retain their ability to display slow relaxation of magnetisation.
