用1,4,7,10,13-五氮十五烷(cpad)作为端基配体,合成了2个同构化合物[{Ni(cpad)}3M(CN)6]2[M(CN)6](ClO4)3·6H2O(M=Cr3+,1;Fe3+,2),其中[M(CN)6]3-通过氰基桥联配位,4个[Ni(cpad)]2+阳离子形成四核簇[{Ni(cpad)}3M(CN)6]3+,游离的[M(CN)6]3-和ClO4-为平衡阴离子。晶体参数如下:1,三方晶系,P3c1空间群,a=1.51441(18)nm,c=3.0807(6)nm,V=6.1189(15)nm3,Z=2;2,三方晶系,P3c1空间群,a=1.49762(17)nm,c=3.0878(5)nm,V=5.9976(14)nm3,Z=2。变温磁化率显示在四核簇内氰基桥联的金属离子之间存在铁磁相互作用。
Two isomorphic compounds [{Ni (cpad)} 3M (CN) 6] 2 [M (CN) were synthesized by using 1,4,7,10,13-pentanedronadecane as the terminal ligand 6] (ClO4) 3.6H2O (M = Cr3 +, 1; Fe3 +, 2), in which [M (CN) 6] 3- is coordinated by cyano bridging and four [cations] The formation of tetranuclear cluster [{Ni (cpad)} 3M (CN) 6] 3+ and free [M (CN) 6] 3- and ClO4- are equilibrium anions. The crystal parameters are as follows: 1. The trigonal system, P3c1 space group, a = 1.51441 (18) nm, c = 3.0807 (6) nm, V = 6.1189 (15) nm3, Z = A = 1.49762 (17) nm, c = 3.0878 (5) nm, V = 5.9976 (14) nm3, Z = 2. The temperature-dependent magnetic susceptibility shows that there is a ferromagnetic interaction between the cyano-bridged metal ions in the tetranuclear cluster.
