Spin crossover phenomena in Fe(II) complexes
The behaviour of spin crossover compounds is among the most striking and fascinating shown by relatively simple molecular species. This review aims to draw attention to the various ways in whichExpand
Insights into the origin of cooperative effects in the spin transition of [Fe(NH2trz)3](NO3)2: the role of supramolecular interactions evidenced in the crystal structure of [Cu(NH2trz)3](NO3)2.H2O.
This hypothesis is strengthened by the crystal structure of 2 and by the absence of crystallographic phase transition for 1 over the whole temperature range of investigation as shown by XRPD, which could be at the origin of the unusually large hysteresis loop displayed by 1. Expand
The Two‐Step Spin Conversion in a Supramolecular Triple Helicate Dinuclear Iron(II) Complex Studied by Mössbauer Spectroscopy
The triple helicate dinuclear iron(II) complex, [Fe-2(L)(3)](ClO4)(4)center dot 2H(2)O (1), previously reported by Tuna et al. (Chem. Eur. J. 2004, 10, 5737), was prepared and characterised byExpand
Dynamics and supramolecular organization of the 1D spin transition polymeric chain compound [Fe(NH2trz)3](NO3)2. Muon spin relaxation.
Insights to the origin of the cooperative effects associated with the spin transition of [Fe(NH(2)trz)3](NO3)2 through muon implantation are presented and fast dynamics have been revealed in the high-spin state of [ Fe(NH[2]trz)]3 with the presence of a Gaussian relaxation mode that is mostly due to the dipolar interaction with static nuclear moments.

Challenges in the synthetic routes to Mn(BH4)2: insight into intermediate compounds.
Crystal structures of two new intermediates, named [{M(Et2O)2}Mn2(BH4)5] (M = Li(+), Na(+)), were elucidated by X-ray diffraction, which contains 2D layers formed by Mn and BH4 groups, linked through the alkali metal atoms coordinated to Et2O. Expand
Spin Crossover in a Supramolecular Fe4II [2×2] Grid Triggered by Temperature, Pressure, and Light
A multiplex electronic switch on the molecular level has been realized by using a tetranuclear FeII complex of the [2×2] grid type. The four metal ions can be switched stepwise between theirExpand
Spin crossover in 1D, 2D and 3D polymeric Fe(II) networks, In Spin crossover in transition metal Compounds I, Eds. P. Gütlich, H.A. Goodwin
In this chapter, structural and spin transition aspects of the most important families of polymeric Fe(II) compounds are reviewed. These coordination compounds contain N-donor heterocyclicExpand
Spin transition charted in a fluorophore-tagged thermochromic dinuclear iron(II) complex.
The first crystal structures of a dinuclear iron(II) complex with three N1,N2-1,2,4-triazole bridges in the high-spin and low-spin states are reported. Its sharp spin transition, which was probedExpand
