Spin-crossover materials: Getting the most from x-ray crystallography.

Spin-crossover systems. In Fe2+ spin crossover systems, an Fe ion surrounded by a cage of ligands similar to the metal in tetrahedral configuration, that can be found in many complex oxides. The metal can assume two distinct spin states: the low spin state with fully occupied tg states and empty eg states (S=0µB), and the high spin state partially occupied tg states.

Photo-switchable systems, such as discrete spin-crossover complexes and bulk iron-cobalt Prussian blue analogues, exhibit, at a given Spin crossover in a catenane supramolecular system. The sections on dinuclear compounds include short background reviews on (i) synergism of SCO and spin-spin magnetic exchange (ii) cooperativity (memory effects) in polynuclear compounds, and (iii) the design of dinuclear SCO compounds using structural and ligand field concepts. Known examples of dinuclear compounds are reviewed and our new. It is shown that the single-ion mechanism of spin crossover under the change in the crystal field does not lead to a thermodynamic phase transition; however, at $T=0$ a quantum phase transition appears.

Cooperativity in Spin Crossover Systems. An Atomistic.

The bistable nature of spin crossover materials coupled to their sensitivity to light irradiation is of particular Configuration diagram of a spin crossover molecule showing the energy barrier variation.

Spin-Crossover Molecular Switches › Department of Chemistry and.

Spin-crossover (SCO) phenomenon is originated from the intrinsic bistability of the d-electron configuration, created by the competition between ligand-field splitting and spin-pairing energies in a. It is shown that single-ion mechanism of spin crossover under change of the crystal field does not lead to a thermodynamic phase transition, however, at T = 0 a quantum phase transition appears.

Optical Waveguiding Organic Nanorods Coated with Reversibly.

Spin crossover systems are potentially more useful than other magnetic molecules because their switching behaviour can occur closer to room temperature, and they are thus candidates for use in. Keywords: spin crossover; iron(III) amphiphile; micelle; Langmuir isotherm; Raman spectroscopy; lyophilization. routes to spin transition systems tend to be relatively facile. The energies of different spin multiplicities of a range of iron complexes are computed using modern density functional theory (DFT) methods of the generalized gradient approximation (GGA; BP86 and OPBE), meta-GGA (TPSS), hybrid meta-GGA (TPSSh), hybrid (B3LYP), and double-hybrid (B2PLYP) types.

Spin Crossover Systems. Philipp Gütlich , Yann Garcia , in Reference Module in Chemistry The phenomenon of spin crossover (SCO), or spin transition, is one of the most attractive and. Spin crossover (SCO) in octahedral transition metal complexes can occur in the d 4 -d 7 electron configurations. 1 While systems with d 5 -d 7 electron configurations (Fe III, Fe II, Co II) have been extensively studied and already matured towards applications, 2-7 the d 4 SCO case (Cr II, Mn III) is only rarely observed and is underdeveloped. 8-14 While several manganese(III) SCO. Spin-transition materials can exhibit thermal hysteresis due to cooperative elastic interactions in between active molecular sites. It results from the coupling of the nonsymmetry-breaking high spin fraction order parameter to the lattice volume strain. However, a symmetry-breaking order parameter responsible for crystallographic phase transition, like a ferroelastic distortion, can also.
