收藏资源简介：
A novel molecular based magnet of three-dimensional (3-D) cyanide-bridged bimetallic assembly, [{(323)Ni}3{FeIII(CN)6}2]n·2nH2O where 323 = N,N‘-bis(3-aminopropyl) ethylenediamine, was synthesized and structurally characterized. The compound crystallizes in the orthorhombic space group Pbca with a = 15.6560 Å, b = 15.2910 Å, c = 50.9120 Å, and Z = 8. The assembly has two intercalated 3-D networks created by FeIII−CN−NiII−NC−FeIII linkages. The ferricyanide anion adopts both facial and meridional arrangements through the linkage. Interesting magnetic properties including 3-dimensional magnetic ordering were revealed. The assembly displays 3-dimensional magnetic ordering below 5.2 ± 0.1 K and field-induced magnetic behavior below 5.1 ± 0.1 K and above 1.15 ±0.05 kOe.
