Interplay between Dopant Species and a Spin-Crossover Host Lattice during Light-Induced Excited-Spin-State Trapping Probed by Electron Paramagnetic Resonance Spectroscopy

Q-band electron paramagnetic resonance (EPR) data conclusively demonstrate that the iron and cobalt centers in the solid solution [Fe­(bpp)<sub>2</sub>]<sub>0.97</sub>[Co­(terpy)<sub>2</sub>]<sub>0.03</sub>[BF<sub>4</sub>]<sub>2</sub> (bpp = 2,6-dipyrazol-1-ylpyridine) undergo allosteric spin-state switching during light-induced excited-spin-state trapping (LIESST) at 20 K and thermal relaxation around 80 K. EPR of [Cu­(terpy)<sub>2</sub>]<sup>2+</sup> and [Cu­(bpp)<sub>2</sub>]<sup>2+</sup>, doped into the same host lattice, also indicates expansion of the copper coordination sphere during LIESST excitation.
