Planar honeycomb-like coordination network {[Ni(cyclam)]3[W(CN)8]2}n (cyclam = 1,4,8,11-tetraazacyclotetradecane) was obtained in the self-assembly reaction of [Ni(cyclam)]2+ and [W(CN)]83-. Its structure is characterized by void channels along the a axis. The compound shows reversible water adsorption in the temperature range of 25-40 degrees C with the formation of {[Ni(cyclam)]3[W(CN)8]2}n.16nH2O, accompanied by single-crystal-to-single-crystal transformation. The structural transformation significantly changes the character of intraplane magnetic exchange interactions.
平面蜂窝状配位网络{[Ni(环胺)]₃[W(CN)₈]₂}ₙ（环胺 = 1,4,8,11 - 四氮杂环十四烷）是在[Ni(环胺)]²⁺与[W(CN)]₈³⁻的自组装反应中得到的。其结构的特征是沿a轴存在空洞通道。该化合物在25 - 40摄氏度的温度范围内表现出可逆的水吸附，形成{[Ni(环胺)]₃[W(CN)₈]₂}ₙ·16nH₂O，同时伴有单晶到单晶的转变。结构转变显著改变了平面内磁交换相互作用的性质。
