Invited talk

A comprehensive understanding of the ligand field and its influence on the degeneracy and population of d-orbitals in a specific coordination environment are crucial for the rational design and enhancement of magnetic anisotropy of single-ion magnets (SIMs). Herein, we report the synthesis and comprehensive magnetic characterization of a highly anisotropic $Co^{II}$ SIM, $[L_2Co](TBA)_2$ ($L$...

Contributed talk

Borazine (B$_3$N$_3$H$_6$) is a heterocyclic compound made of alternating boron and nitrogen atoms, known as the "inorganic benzene" because the C=C and B=N bonds are isostructural and isoelectronic. Despite such similarities with benzene, the borazine ring has very different electronic properties due to significant differences in electronegativity between the boron and nitrogen atoms.

42. Spin-density studies of the multiferroic metal–organic compound [NH2(CH3)2][FeIIIFeII(HCOO)6]

Molecular magnetism

Poster

Metal–organic frameworks combining two or more properties have been the focus of interest of several research groups in the last few decades. A good approach to achieve this combination has been the design of perovskite-like metal–organic frameworks where a three-dimensional network made of metallic centres linked through organic ligands, which presents magnetic order, also accommodates...

52. Spin-resolved electron density on a tri-radical borazine

Molecular magnetism

Poster

The first experimental electron density study of a borazine core was conducted by Guzman et al.[1]. This study allowed for the analysis of charge delocalization (Figure 1.b) in the core of an unsubstituted borazine and confirmed the very low aromaticity of this core compared to a benzene ring.\\
Recently, the D. Luneau team focused on the magneto-structural properties of radicals based on a...
