Oxidative Addition of Halogens on Open Metal Sites in a Microporous Spin‐Crossover Coordination Polymer

Abstract

Mixing with the guests: Exposure of the porous spin-crossover framework {Fe(pz)[PtII(CN)4]} to X2 (pz=pyrazine; X2=Cl2, Br2, and I2) leads to incorporation of the halides in the coordinatively unsaturated [PtII(CN)4]2− moieties through oxidative addition, thus affording the mixed-valence series {Fe(pz)[PtII/IV(CN)4(X)]}, which features quite distinct cooperative spin-transition properties.
