| Abstract
| - A two-dimensional honeycomb-like network reversibly adsorbs water into channel-like pores, retaining its crystalline form. The process causes structural and magnetic changes.
- Planar honeycomb-like coordination network {[Ni(cyclam)]3[W(CN)8]2}n (cyclam = 1,4,8,11-tetraazacyclotetradecane) wasobtained in the self-assembly reaction of [Ni(cyclam)]2+ and[W(CN)]83-. Its structure is characterized by void channels alongthe a axis. The compound shows reversible water adsorption inthe temperature range of 25−40 °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 exchangeinteractions.
