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


  • We thank Dr. M. Shiro and Dr. A. Kishi (Rigaku Corp.) for their technical assistance with the X-ray measurements; pyz=pyrazine.

CO2is 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).
