Abstract The synthesis, structure, magnetic, and luminescence properties investigations of four new cage‐like lanthanide‐based silsesquioxanes (Cat) 2 [(PhSiO 1.5 ) 8 (LnO 1.5 ) 4 (O)(NO 2.5 ) 6 (EtOH) 2 (MeCN) 2 ] (where Cat + =Et 4 N + , PPh 4 P + and Ln 3+ =Eu 3+ , Tb 3+ and (Ph 4 P) 4 [(PhSiO 1.5 ) 8 (TbO 1.5 ) 4 (O) 2 (NO 2.5 ) 8 ]⋅10MeCN are reported. They present an unusual prism‐like topology of cage architectures and lanthanide‐characteristic emission, which makes them the first luminescent cage‐like lanthanide silsesquioxanes. One of the Tb 3+ ‐based cages presents a magnetic spin‐flip transition.
