Three-Way Crystal-to-Crystal Reversible Transformation and Controlled Spin Switching by a Nonporous Molecular Material

Abstract: Porous materials capable of hosting external molecules are paramount in basic and applied research. Nonporous materials able to incorporate molecules via internal lattice reorganization are however extremely rare since their structural integrity usually does not resist the guest exchange processes. The novel heteroleptic low-spin Fe(II) complex [Fe(bpp)(H2L)](ClO4)2·1.5C3H6O (1; bpp = 2,6-bis(pyrazol-3-yl)pyridine, H2L = 2,6-bis(5-(2-methoxyphenyl)pyrazol-3-yl)pyridine) crystallizes as a compact discrete, nonp… Show more

“…Besides, if this transition occurs with hysteresis a memory effect is conferred. In very recent years there is a renaissance of SCO materials in molecular magnetism [6][7][8][9][10][11][12] because, in contrast with other bistable species such as single molecule magnets, [13,14] SCO may occur at room temperature.…”

“…Indeed, magnetic materials that show single-crystal-to-single-crystal (SCSC) transformation are tremendously valuable for understanding the mechanism of the transformation and the magnetostructural correlations, but are extremely scarce. [13,[19][20][21][22][23][24][25][26][27][28] Here we present for the first time a two-consecutive guest inclusion-release process occurring via SCSC that is accompanied by modification in the magnetic behavior. The first process involves a polymeric-to-molecular material SCSC transformation, whereas the second SCSC process encompasses the reformation of a coordination polymer.…”
