Anion-Dependent Self-Assembly of Near-Infrared Luminescent 24- and 32-Metal Cd–Ln Complexes with Drum-like Architectures

Two series of 4d–4f clusters [Ln₈Cd₂₄L₁₂­(OAc)₄₈] and [Ln₆Cd₁₈L₉Cl₈₍₁₀₎­(OAc)₂₈₍₂₆₎] (Ln = Nd, Gd, Er, and Yb) with novel drum-like structures were prepared using a flexible Schiff base ligand. Their NIR luminescence properties were determined.
