Abstract

We previously reported that a single crystal of [Co(en)₃]Cl₃ shows gas adsorbency for various gases and organic vapors accompanying channel expansion in its crystal structure. To investigate the possibility of a single crystal of tris-ethylenediamine metal complex as an ionic single-crystal host for vapor adsorption, a series of adsorbencies of single crystals of [M^III(en)₃]Cl₃ (M = Co 1, Cr 2, Rh 3, Ir 4) were studied. All complexes have channels in their crystal structures, which dynamically and reversibly change size with vapor adsorption and show similar vapor adsorbency similar to the adsorption behavior of [Co(en)₃]Cl₃.
