A new moisture-sensitive metal-coordination solids {[Cd(C4O4)(bipy)(H2O)(2)]center dot 3H2O}(infinity) (bipy=4,4 '-bipyridine)

摘要

A new mixed-ligands metal-coordination polymer, [Cd(C4O4)(bipy)(H2O2)(2)] (1), (bipy = 4,4'-bipyridine), was synthesized under hydrothermal condition and characterized by X-ray diffraction method. A three-dimensional interpenetrating network with one-dimensional channels intercalating water molecules undergoes a reversible hydration-dehydration process upon a cooling-heating cycles associated with distinct color change and structural variation.
