Methanol adsorption into the porous 2D bimetallic coordination network {Ni(cyclam)W(CN)(8)}(n) (cyclam = 1,4,8,11-tetraazacyclotetradecane) causes significant modification of its structure and magnetic properties. Fully reversible transformations between the three states of the network: anhydrous, hydrated and methanol-modified are observed with the transition to the magnetic ordered state at T(c) equal to 4.9 K, 8.3 K and 11.4 K respectively. All three phases have a metamagnetic character but the methanol-modified one most easily turns to ferromagnetic and shows a hysteresis loop with coercivity field of 250 Oe. The differences in magnetic behaviour of the anhydrous and guest-induced forms of the compound are discussed in terms of changes in the structure: CN-bridge geometry and distance between the layers.
甲醇吸附到多孔二维双金属配位网络{Ni(cyclam)W(CN)(8)}（n）（cyclam=1,4,8,11-四氮杂环十四烷）中会显著改变其结构和磁性质。该网络的三种状态：无水、水合和甲醇修饰之间的完全可逆转变，分别在转变到磁有序态时观察到 T(c)等于 4.9 K、8.3 K 和 11.4 K。所有三个相都具有抗磁性，但甲醇修饰的相最容易转变为铁磁性，并显示出具有 250 Oe 矫顽力场的滞后环。无水和客体诱导化合物的磁行为差异是根据结构变化来讨论的：CN-桥几何形状和层之间的距离。
