CO₂-actuated spin transition tuning in an interdigitated Hofmann-type coordination polymer.

ABSTRACT: The increased anthropogenic emission level of CO₂ urges the development of CO₂-responsive materials, but is it possible to regulate the inherent electronic properties through weak physisorption of a ubiquitous gas such as CO₂? Herein, we intended to answer this imperative question by the first case of CO₂-actuated variable spin-state stabilisation in an interdigitated Hofmann-type coordination polymer [Fe^IIPd(CN)₄L₂] (1, L = methyl isonicotinate), showing a wide shift in transition temperature (T _eq) from 178 K at P _CO2 = 0 kPa to 229 K at P _CO2 = 100 kPa. Interestingly, the emergence of a stepped behaviour in the heating process below
