Iron(II) spin crossover complexes with a sulfur rich ligand.

Ligand substitution eﬀects on spin crossover. The observation of spin crossover in these FeII 2 complexes, in conjunction with the dearth of studies that probe electronic eﬀects on spin crossover, prompted us to investigate how the substitution pattern of benzoquinonoid-bridging ligands aﬀects spin crossover in FeII 2 complexes. Toward.

Spin crossover in cis manganese(III) quinolylsalicylaldiminates.

We synthesized an Fe(II) [2 × 2] molecular grid with pyridyl-substituted bis-terdentate ligands. The molecular grid showed abrupt spin crossover between fully high-spin and fully low-spin states in a narrow temperature width of ∼10 K. The spin crossover event also included a first-order structural phase transition, in which the dielectric constant jumped atypically toward a low-spin state.

Spin crossover in iron(II) and cobalt(II) complexes including.

A comparison with the literature-reported spin crossover iron(II) complexes in N 4 S 2 coordination sphere containing NCE co-ligands has been conducted as well, finding that, as previously reported, the Fe−N−C(E) bond angle is diagnostic for determining the spin lability of the metal complexes, and in addition we have found that the N−C(E. Variable temperature magnetic susceptibility measurements indicate that 1+ and 2+ undergo gradual half spin crossover, despite having cis O donors. DFT calculations reveal a small HS-LS gap in the MnIII systems consistent with spin crossover and provide insight into the ligand design necessary for spin crossover in cis-N4O2 MnIII compounds. It is revealed that multiple factors dominate the spin-state behaviour in the solid state. This work provides deep insight into the effect of ligand symmetry on the spin transition behaviour in spin crossover compounds. It demonstrates that molecular symmetry should be considered in the design of spin crossover compounds.

FeIII Spin‐Crossover Complexes with Photoisomerizable Ligands.

Herein, we examine the magnetic and redox properties of three new iron (II) complexes of this new ligand with an N 4 O 2 coordination sphere that is usually used for the synthesis of spin crossover complexes. The electronic properties of one complex are examined in more detail by using impedance spectroscopy. II. RESULTS AND DISCUSSION. Abstract Spin crossover compounds are a diverse class of switchable materials with applications ranging from data storage devices to sensors. Iron (III) spin crossover complexes have received renewed attention over the last 10 years with an increasing number of abrupt and hysteretic spin crossover systems discovered.

At the outset, the primary focus of this Ph.D. project has been directed towards the synthesis of new 2,2'-dipyridylamino(dpa)- and 1,2,4-triazole(trz)- based ligands to be incorporated into spin crossover (SCO) iron(II) complexes. Initial aims sought the synthesis of a wide and diverse range of SCO compounds containing novel dpa- and trz-based ligands in order to determine what sort of. The prediction of this behavior has been attempted by many authors. It is, however, made very difficult because spin crossover (SCO), as it is called, occurs most often in the solid state, where besides complexes, counter ions, and solvents are also present in many cases. Intermolecular interactions definitely play a major role in SCO.

An Iron(II) Spin Crossover Complex with a Maleonitrile Schiff base‐like.

In addition to the aforementioned interests, it is well known that pyrazole- and pyrazolate-derived ligands can generate iron(II) spin crossover (SCO) active complexes , , in which the paramagnetic t 2g 4 e g 2 high spin state (HS) can be switched to the diamagnetic t 2g 6 low spin state (LS) by means of an external stimulus like temperature, pressure, light or.

PDF Electronic Eﬀects of Ligand Substitution on Spin Crossover in a Series.

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.

As spin transition compounds, dinuclear complexes are of particular interest, since they potentially reveal a two-step spin crossover (SCO), switching between the high spin–high spin [HS-HS], the high spin–low spin [HS-LS], and the low spin–low spin.

Temperature fluctuation control with a switchable spin.

Both 1 and 2 exhibit a low spin (S = 1/2) to high spin (HS, S = 5/2) transition in the solid state. In solution at room temperature both complexes are predominantly HS. Upon exposure to 310 (trans cis) and 440 nm radiation (cis trans) the free and coordinated 3- and 4-azpy ligands undergo a reversible cis–trans isomerization. Spin crossover (SCO) is a phenomenon seen in 3d4-3d7octa- hedral metal complexes when the ligand eld is 'just right' so that the application of an external stimulus, including temperature, pressure, light irradiation and guest molecules, causes a reversible switch of spin state, from HS to LS.1-3This..

Photoinduced spin crossover offers a convenient handle on the spin states and magnetic interactions within a material, which is promising for the development of photoresponsive nanomagnets. Now, a.

Iron(II) Spin Crossover Systems with Multidentate Ligands.

All the three derivatives are spin crossover (SCO) active, showing complete one-step spin conversion. The SCO midpoint temperatures ( T 1/2 ) are 193 K for 1-S , 226 K for 1-Se , and 330 K for 1-BH 3 , which are among the highest values for the homologous Fe(II)-NCE complexes with comparable tetradentate ligands. In some cases, ligands can create an energy field in which the value of the spin pairing energy (P) and the splitting energy of the ligand field (∆ o) are approximately the same (intersection point, crossover), so the influence of an external stimulus can lead to a reversible switch between HS and LS-states (Hauser 2004).

The past decade has witnessed intense research activity in the area of Fe(II) spin crossover coordination polymers, which are structurally diverse and functionally intriguing materials. In this endeavor, a less exploited series of ligands have been selected among various N-donor triazole and tetrazole molecules.

Introduction The synthesis of new coordination polymers (CP) with interesting properties constitutes a hot topic given the interesting properties that these materials may show. Thus, although many CP have.
