Spin-Crossover Complexes [PDF]

Inorganics, 2018
Spin-crossover (SCO) is a spin-state switching phenomenon between a high-spin (HS) and low-spin (LS) electronic configurations in a transition metal center.

Mosaicity of Spin-Crossover Crystals [PDF]

Crystals, 2018
Real crystals are composed of a mosaic of domains whose misalignment is evaluated by their level of “mosaicity” using X-ray diffraction. In thermo-induced spin-crossover compounds, the crystal may be seen as a mixture of metal centres, some ...

Atomically tweaking spin-crossover cooperativity to augment molecular memory density [PDF]

Nature Communications
Spin-crossover complexes are promising candidates for molecular bits owing to their magnetic bistability. However, it’s a formidable challenge to turn densely packed spin-crossover molecules into high-density bits due to cooperative switching dynamics ...

Iron(II) Spin Crossover Complexes with 4,4′-Dipyridylethyne—Crystal Structures and Spin Crossover with Hysteresis

Molecules, 2020
Three new iron(II) 1D coordination polymers with cooperative spin crossover behavior showing thermal hysteresis loops were synthesized using N2O2 Schiff base-like equatorial ligands and 4,4′-dipyridylethyne as a bridging, rigid axial linker. One of

Cooperative spin crossover leading to bistable and multi-inert system states in an iron(III) complex [PDF]

Nature Communications
Cooperativity among spin centres has long been the royal road in spin crossover (SCO) research to impose magnetic bistability in terms of thermal hysteresis.

Elastocaloric, barocaloric and magnetocaloric effects in spin crossover polymer composite films [PDF]

Nature Communications
Giant barocaloric effects were recently reported for spin-crossover materials. The volume change in these materials suggests that the transition can be influenced by uniaxial stress, and give rise to giant elastocaloric properties.

Locking and Unlocking the Molecular Spin Crossover Transition

Advanced Materials, 2017
AbstractThe Fe(II) spin crossover complex [Fe{H2B(pz)2}2(bipy)] (pz = pyrazol‐1‐yl, bipy = 2,2′‐bipyridine) can be locked in a largely low‐spin‐state configuration over a temperature range that includes temperatures well above the thermal spin crossover temperature of 160 K.

Modeling Spin-Crossover Dynamics [PDF]

Annual Review of Physical Chemistry, 2021
In this article, we review nonadiabatic molecular dynamics (NAMD) methods for modeling spin-crossover transitions. First, we discuss different representations of electronic states employed in the grid-based and direct NAMD simulations. The nature of interstate couplings in different representations is highlighted, with the main focus on nonadiabatic ...
