Two organically templated nickel sulfates of the compositions [C(4)N(2)H(12)][Ni(3)F(2)(SO(4))(3)(H(2)O)(2)] (I) and [C(4)N(2)H(12)][Ni(2)F(4)(SO(4))H(2)O] (II) with open architectures have been synthesized under hydro/solvothermal conditions in the presence of piperazine. I has a layered structure formed by sinusoidal chains comprising hexameric units, whereas II has a three-dimensional structure with 10-membered channels. The layered Ni(II) sulfate, I, is ferrimagnetic, exhibiting hysteresis at low temperatures. The three-dimensional Ni(II) sulfate, II, is essentially paramagnetic. We have also obtained layered compounds isostructural with I containing other amines.
在水热/溶剂热条件下,以哌嗪为模板合成了两种具有开放结构的有机模板硫酸镍,其组成为[C(4)N(2)H(12)][Ni(3)F(2)(SO(4))(3)(H(2)O)(2)](I)和[C(4)N(2)H(12)][Ni(2)F(4)(SO(4))H(2)O](II)。I具有由包含六聚体单元的正弦链形成的层状结构,而II具有带有10元通道的三维结构。层状硫酸镍(II),I,是亚铁磁性的,在低温下表现出磁滞现象。三维硫酸镍(II),II,基本上是顺磁性的。我们还获得了与I同构的包含其他胺的层状化合物。
