A novel alb metalloring organic framework with a {Ni12Gd24} cage exhibiting a significant magnetocaloric effect†
Abstract
With the aid of a bifunctional 6-mercaptonicotinic acid ligand, a novel {Ni12Gd24} cage-based (6, 12)-c alb–MROF that is assembled from a {Gd4(OH)4(COO)6} trigonal-prism building unit and a {Ni6S12} hexagonal-prism molecular building block has been synthesized for the first time. It exhibits a large MCE value of 29.86 J kg−1 K−1 for ΔH = 8 T at 2 K.
