Abstract

Q-band electron paramagnetic resonance (EPR) data conclusively demonstrate that the iron and cobalt centers in the solid solution [Fe(bpp)₂]_0.97[Co(terpy)₂]_0.03[BF₄]₂ (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)₂]²⁺ and [Cu(bpp)₂]²⁺, doped into the same host lattice, also indicates expansion of the copper coordination sphere during LIESST excitation.
