A monotropic smectic A phase is exhibited by adducts of tris( β ‐diketonato)lanthanide( III ) complexes with a non‐mesomorphic salicylaldimine Schiff base as Lewis base. Only four terminal alkyl chains were necessary in the Schiff base to induce mesomorphism in [La(dbm) 3 ] (see formula). Hdbm = 1,3‐diphenyl‐1,3‐propanedione (dibenzoylmethane).
