Autor: Joachim Kusz, C. Matthias Grunert, Prashant Sonar, Yongli Wei, Philipp Gütlich, A. Dieter Schlüter

Publikováno v: European Journal of Inorganic Chemistry. 2008:1613-1622

The ligands G1- and G2-oligo (benzyl ether) (PBE) dendrons and their iron(II) complexes [Fe(Gn-PBE)3]A2·xH2O (with n = 1, 2 and A = triflate, tosylate) were prepared. The magnetic properties of the complexes were investigated by a SQUID magnetometer

Iron(II) complexes obtained from tetradentate, rigid, linear N4 ligands have been investigated to appraise the influence of steric effects and the impact of trans-coordinated anions on the spin-transition behavior. As expected, the well-designed liga

Spin- and phase transition in the spin crossover complex [Fe(ptz)6](BF4)2 studied by nuclear inelastic scattering of synchrotron radiation and by DFT calculations

Autor: Juliusz A. Wolny, Alfred X. Trautwein, C. Matthias Grunert, Aleksandr I. Chumakov, Ulrich Ponkratz, Hauke Paulsen, Lars H. Böttger, Philipp Gütlich, Joachim Kusz, V. Rusanov

Publikováno v: Chemical Physics Letters. 429:189-193

Nuclear inelastic scattering (NIS) spectra of [Fe(ptz) 6 ](BF 4 ) 2 (ptz = 1- n -propyl-tetrazole) have been measured for five phases differing in spin state and crystallographic structure. Different spectral patterns have been found for the low-spin

Synthesis and characterisation of tetrazole compounds: 3 series of new ligands representing versatile building blocks for iron(II) spin-crossover compounds

Autor: C. Matthias Grunert, Johannes Schweifer, Peter Weinberger, Christina Hampel, Wolfgang Linert, Kurt Mereiter, Arno F. Stassen

Publikováno v: Journal of Molecular Structure. 733:41-52

New tetrazole compounds were synthesized and characterised by NMR and FTIR spectroscopy as well as by single crystal X-ray diffraction. We present in this paper mono- and ditetrazoles, which represent a versatile class of building blocks for the form

Mixed spin-state [HS-LS] pairs in a dinuclear spin-transition complex: confirmation by variable-temperature 57Fe Mössbauer spectroscopy

Autor: C. Matthias Grunert, Hartmut Spiering, Jonathan A. Kitchen, Sally Brooker, Philipp Gütlich, S. Reiman

Publikováno v: Angewandte Chemie (International ed. in English). 47(16)

Exquisite sensitivity of Mossbauer spectroscopy for tiny local molecular distortion is demonstrated in [FeII2(pmat)2](BF4)4?DMF: high-spin (HS) iron(II) in [HS-HS] and in [LS-HS] (low-spin–high-spin) pairs is clearly distinguished (see picture) for

[Fe(bpp)2][Pt(ox)2].H2O (with bpp=2,6-bis(pyrazol-3-yl)-pyridine and ox=oxalate) was prepared, and its spin crossover behavior was characterized. The two-step spin transition behavior changes over several cycles. The original behavior is restored whe
