Magnetic Anisotropy in Pentacoordinate NiII and CoII Complexes: Unraveling Electronic and Geometrical Contributions
Benjamin Cahier,Mauro Perfetti,Mauro Perfetti,Georges Zakhia,Daoud Naoufal,Fatima El-Khatib,Régis Guillot,Eric Rivière,Roberta Sessoli,Anne-Laure Barra,Nathalie Guihéry,Talal Mallah +11 more
TL;DR: The geometry of the pentacoordinate complexes was found to be the result of a compromise between the electronic configuration of the metal ion and the structure-orienting effect of the Me4 cyclam macrocycle, and the orientation of the anisotropy axes is mainly dependent on the architecture of the complexes.

Tools for Predicting the Nature and Magnitude of Magnetic Anisotropy in Transition Metal Complexes: Application to Co(II) Complexes
TL;DR: In this article, the authors address the question of the excited states that are mainly responsible for the magnitude and nature of the magnetic anisotropy in high-spin mononuclear transition metal complexes.

Design and Magnetic Properties of a Mononuclear Co(II) Single Molecule Magnet and Its Antiferromagnetically Coupled Binuclear Derivative
Fatima El-Khatib,Fatima El-Khatib,Benjamin Cahier,Feng Shao,Maurici López-Jordà,Régis Guillot,Eric Rivière,Hala Hafez,Zeinab Saad,Jean-Jacques Girerd,Nathalie Guihéry,Talal Mallah +11 more
TL;DR: Analysis of the effect of the |J/D| ratio on the magnetic behavior of the binuclear complex and prediction of the optimum range of values for the complex to behave as two weakly interacting SMMs are reported.

Design of a Binuclear Ni(II) Complex with Large Ising-type Anisotropy and Weak Anti-Ferromagnetic Coupling
Fatima El-Khatib,Fatima El-Khatib,Benjamin Cahier,Maurici López-Jordà,Régis Guillot,Eric Rivière,Hala Hafez,Zeinab Saad,Jean-Jacques Girerd,Nathalie Guihéry,Talal Mallah +10 more
TL;DR: It is shown that a slight distortion of the coordination sphere of Ni(II) from spy to tbp leads to an Ising-type anisotropy and a weak anti-ferromagnetic exchange coupling through the imidazolate bridge.

XAS and XMCD Reveal a Cobalt(II) Imide Undergoes High-Pressure-Induced Spin Crossover
Nadejda Bouldi,Matteo Mannini,Marius Retegan,Reece G. Miller,Benjamin Cahier,Philippe Sainctavit,Nathalie Guihéry,Talal Mallah,Delphine Cabaret,D. Gouéré,François Baudelet,L. Nataf,Fabrice Wilhelm,Francois Guillou,Andrei Rogalev,Nicolas Suaud,Sally Brooker,Amélie Juhin +17 more
TL;DR: In this paper , the spin crossover transition in two molecular Co2+ bis-imide compounds, Co(dpzca)2 and Co(pypzca), was investigated using temperature and pressure-dependent element selective X-ray absorption spectroscopy (XAS and XMCD) measurements.
