Carbon Dioxide Inclusion Phases of a Transformable 1D Coordination Polymer Host [Rh₂(O₂CPh)₄(pyz)]_<i>n</i>

Abstract

CO2 is included: The one-dimensional coordination polymer host [Rh2(O2CPh)4(pyz)]n (pyz=pyrazine; see picture, left) undergoes a reversible phase transition under cooling that is induced by CO2 adsorption to give an inclusion complex, in which up to three CO2 molecules per polymer unit reside within channels (right).
