Abstract

Two gadolinium clusters, [Gd ₂ (H ₃ L) ₂ (NO ₃ ) ₂ ](NO ₃ ) ₂ (1) and [Gd ₃ (HL)(H ₂ L)(NO ₃ ) ₄ ]·C ₂ H ₅ OH (2) (H ₄ L = N,N,N′,N′-tetrakis(2-hydroxyethyl)ethylenediamine), were synthesized and characterized with different solvents. The magnetic properties of 1 and 2 were recorded and studied in detail. 1 is a centrosymmetric binuclear Gd ₂ cluster, adopting a P1 space group (point group 1), and exhibits a strong magnetocaloric effect (MCE) entropy with −ΔS _m of 27.50 J kg ⁻¹ K ⁻¹ . 2 crystallizes in the Pna2 ₁ space group (polar point group mm2) through solvent modulation and contains an asymmetric trinuclear Gd ₃ cluster. Magnetic and ferroelectric investigations of 2 reveal a large change in the magnetocaloric effect entropy with −ΔS _m of 30.22 J kg ⁻¹ K ⁻¹ , ferroelectric hysteresis and dielectric anomalies.
