Journal Article
Structural aspects of spin crossover. Example of the [FeIILn(NCS)2] complexes
TL;DR: In this paper, structural modifications due to spin crossover are first estimated, these include the expansion and the distortion of the FeN 6 octahedron, the isotropic and the anisotropic changes of the unit cell.
Journal ArticleDOI
Synthesis, crystal structure, EXAFS and magnetic properties of Catena [mu-tris(4-(2'-hydroxy-ethyl)-1,2,4-triazole-N1,N2) copper(II)] bis (perchlorate) trihydrate. Relevance with the structure of the Fe(II) 1,2,4-triazole spin transition molecular materials
Yann Garcia,Petra J. van Koningsbruggen,Georges Bravic,Philippe Guionneau,Daniel Chasseau,Giovanni Luca Gascarano,Jacques Moscovici,Katia Lambert,Alain Michalowicz,Olivier Kahn +9 more
TL;DR: In this paper, the first structurally characterized metal(II) chain compound containing triple N1,N2-1,2,4-triazole bridges was solved at 298 K by single-crystal X-ray analysis.
Journal ArticleDOI
Structural approach of the features of the spin crossover transition in iron (II) compounds
Philippe Guionneau,Jean-François Létard,Dimitrii S. Yufit,Daniel Chasseau,Georges Bravic,Andrés E. Goeta,Judith A. K. Howard,Olivier Kahn +7 more
TL;DR: In this paper, the crystal structures of four Fe(PM-L) compounds were determined, both in high and low spin state, and the crystal packing is similar in all of the structures except that the intermolecular interactions, classified as intra- and inter-sheet, show some differences.
Journal ArticleDOI
Crystal structure, magnetic properties, and 57Fe Mössbauer spectroscopy of the two-dimensional coordination polymers [M(1,2-bis(1,2,4-triazol-4-yl)ethane)2(NCS)2] (MII = Fe, Co).
TL;DR: The surprising absence of spin-crossover behavior for this Fe(II)-1,2,4-triazole polymeric coordination compound that has been confirmed by pressure experiments up to approximately 12 kbar and by light irradiation experiments at 10 K is discussed on the basis of its structural features.
Journal ArticleDOI
Crystal structures and non-linear optical properties of borane derivatives
Minh Lequan,Rose Marie Lequan,Kathleen Chane Ching,Marguerite Barzoukas,Alain Fort,Hajji Lahoucine,Georges Bravic,Daniel Chasseau,J. Gaultier +8 more
TL;DR: In this article, the trivalent boron group is shown to be an efficient electron acceptor compared to other known acceptors such as the nitro group, and the EFISH technique is used to calculate dipole moments in the ground state and the hyperpolarizability coefficient βo was measured for each derivative.
