资源简介：
A new tricyanoferrate(III) building block and a trinuclear single-molecule magnet derivative are described. The treatment of a 2:1 ratio of [NEt4][(Tp*Bn)FeIII(CN)3]·H2O·MeOH [1; Tp*Bn = tris(3,5-dimethyl-4-benzyl)pyrazolylborate] with nickel(II) trifluoromethanesulfonate gives {[(Tp*Bn)FeIII(CN)3]2[NiII(DMF)4]}·2DMF (2; DMF = N,N-dimethylformamide). The symmetry-equivalent FeIIILS ions lead to a favorable alignment of anisotropy tensors (i.e., Fe···B axes) in 2, and an energy barrier of Δeff/kB = 16.7 K is found for the ST = 2 complex.
