Surface induces different crystal structures in a room temperature switchable spin crossover compound.
We investigated the influence of surfaces in the formation of different crystal structures of a spin crossover compound, namely [Fe(L)2] (LH: (2-(pyrazol-1-yl)-6-(1H-tetrazol-5-yl)pyridine), which is a neutral compound thermally switchable around room temperature. We observed that the surface induces the formation of two different crystal structures, which exhibit opposite spin transitions, i.e...
متن کاملDilution Effects in a Spin Crossover System, Modelled in Terms of Direct and Indirect Intermolecular Interactions
We have studied by ~7Fe Môssbauer spectroscopy and magnetic measurements trie spin transition exhibited by the series: [Fe~coi-~ (4,4'-bis-1,2,4-triazole)2 (NCS)2].H20, consisting of a spin-crossover iroil(II) system diluted in a high-spin cobalt(II) matrix. We performed Monte Carlo simulations of the thermal variation of the high-spin fraction, using a two-level Ising-type Hamiltonian. A good ...
متن کاملSwitchable slow relaxation of magnetization in the native low temperature phase of a cooperative spin-crossover compound.
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 ca...
متن کاملA Spin Crossover Transition in a Mn(II) Chain Compound
Three new compounds have been synthesized and characterized with Fe(II), Co(II) and Mn(II), the polynitrile anionic ligand 1,1,3,3-tetracyano-2-(3-hydroxypropoxy)-propenide (tcnopr3OH ́) and the co-ligand 4,41-bipyridine (4,41-bpy). The Fe(II) compound, formulated as [FeII(tcnoprOH)2(H2O)2(4,41-bpy)2] (1), contains monomeric complexes where the Fe(II) ion is coordinated to two trans polynitrile ...
