将Ni(tn)(CIO4)2的水溶液和K2[Ni(CN)4]·H2O的水溶液在U形管中通过扩散反应,得到了一种结构新颖的三维蜂窝状配位聚合物{[Ni(tn)][Ni(CN)4]·2H2O}n(tn为1,3-丙二胺).该化合物属单斜晶系,空间群为C2/c,晶胞参数为n=1.2014(2)nm,b=0 8942(2)nm,c=1.2645(3)nm,α=90°,β=108.76(2)°,γ=90°,V=1.2863(5)nm3和Z=4.该化合物由四配位Ni与六配位Ni通过氰根离子桥联而形成三维无限伸展的蜂窝状结构,其中四配位的Ni(2)离子为C配位平面四方构型,六配位的Ni(1)离子为N配位八面体构型.变温磁化率测定表明,在分子内部存在弱的反铁磁相互作用.

A new three-dimensional cyanide-bridged coordination polymer, {[Ni(tn)][Ni(CN)4·2H2O}n(where tn=1,3-diaminopropane), has been prepared from the reaction of [Ni(tn)(ClO4)2] with K2·H2O in water. The compound crystallizes in the monoclinic space group C2/c with the cell dimensions of a=1.2014(2) nm, b=0.8942(2) nm, c=1.2645(3) nm, α=90°, β=108.76(2)°, γ=90°, V=1.2863(5) nm3 and Z=4. The compound assumes a three dimensional honeycomb like structure. Magnetic susceptibility measurements indicate the presence of a weak intramolecular antiferromagnetic interaction.
