title: Spin-crossover modification through selective CO2 sorption.
abstract: We present a spin-crossover Fe(II) coordination polymer with no permanent channels that selectively sorbs CO2 over N2. The one-dimensional chains display internal voids of ∼9 Å diameter, each being capable to accept one molecule of CO2 at 1 bar and 273 K. X-ray diffraction provides direct structural evidence of the location of the gas molecules and reveals the formation of O═C═O(δ(-))···π interactions. This physisorption modifies the spin transition, producing a 9 K increase in T1/2.
