title: Unique (3,12)-connected coordination polymers displaying high stability, large magnetocaloric effect and slow magnetic relaxation.
abstract: Two unique 3D coordination polymers based on octahedral [Ln6] (Ln = Gd (), Dy ()) clusters as nodes were synthesized, exhibiting a novel (3,12)-connected topology with the symbol of (4(20)·6(26)·8(20))(4(3))4. The magnetic studies reveal that shows a -ΔSm = 46.6 J kg(-1) K(-1), falling among the largest values known to date, and displays slow magnetic relaxation behavior. Both and have high thermal and solvent stabilities.
