[Ln7(DPA)5(NA)3(μ3-OH)8(H2O)3]·2.5H2O [H2DPA =二苯甲酸；海航=烟酸；Ln = Gd (1), Dy(2)]，并进行了结构表征。他们很少看到由混合H2DPA和HNA配体的七核三角形-反棱镜镧系元素簇构建的3D框架的例子。1和2都表现出典型的反铁磁相互作用。此外，配合物1具有34.15 J kg(-1) K（-1）的大磁热效应。
Two 3D lanthanide frameworks, [Ln7(DPA)5(NA)3(μ3-OH)8(H2O)3]·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(-1) K(-1).
