Abstract

Two solvated cobalt(ii) terpyridine complexes, [Co(MeO-terpy)₂](BF₄)₂·H₂O (1·H₂O) and [Co(MeO-terpy)₂](BF₄)₂·acetone (1·acetone) were prepared. Annealing each of these complexes resulted in the formation of two desolvated species, 1 and 1′, respectively. 1·H₂O and 1 exhibited two-step and gradual SCO. The compound 1·acetone has high-spin at all temperatures and 1′ undergoes a reverse spin transition due to a phase change.
