Two 3D lanthanide frameworks, [Ln₇(DPA)₅(NA)₃(渭₃-OH)₈(H₂O)₃]路2.5H₂O [H₂DPA = diphenic acid; HNA = nicotinic acid; Ln = Gd (1), Dy (2)], were synthesized and structurally characterized. They were rarely seen examples of 3D frameworks constructed from heptanuclear trigonal-antiprismatic lanthanide clusters with mixed H₂DPA and HNA ligands. Both 1 and 2 show typical antiferromagnetic interactions. Additionally, complex 1 possesses a large magnetocaloric effect of 34.15 J kg^鈥? K^鈥?.
