Switchable slow relaxation of magnetization in the native low temperature phase of a cooperative spin-crossover compound.

ABSTRACT: The implementation of single-molecule magnet properties in spin crossover materials is sought as a unique source of magnetic multistability at the molecular level. Examples however remain extremely scarce, in part due to the diamagnetic state of most Fe(ii) spin crossover materials at low temperatures. We have studied the complex [Fe(mtz)₆](CF₃SO₃)₂ (mtz = 1-methyltetrazole) as a tantalizing candidate of such coexistence, due to its known partial spin crossover and therefore paramagnetic native low temperature phase. The single-crystal structures of [Fe(mtz)₆](CF₃SO₃)₂ reported here allow rationalizing its peculiar cooperative spin-crossover behavior. Importantly, the high-spin Fe crystallographic sites
