The rational design of magnetic and fluorescent bifunctional materials is attracting increasing interest. In this study, two mononuclear Fe(ii) complexes, namely [Fe(L)2(NCS)2] (1) and [Fe(L)2(NCSe)2] (2) are synthesised by combining a spin-crossover unit and a fluorescent ligand (naphth-1-yl)-N-(3,5-di(pyridin-2-yl)-4H-1,2,4-triazol-4-yl)methanimine (L) to achieve bifunctionality. Single-cryst...

Photomagnetic storage and retrieval of information in the megahertz frequency range utilizes a ferrimagnetic material as the storage medium in conjunction with parametric excitation of infrared exchange resonance spinwave modes, by means of signal-modulated polarized coherent radiation, for example, from a COz laser at 10.6 micrometer length, focused to the storage medium. Parametric excitation...

Three new ionic salts containing [M(CN)8]4? (M = MoIV and WIV) were prepared using large complex cations based on a non-conventional motif built with the tris(2-aminoethyl)amine (noted hereafter tren) ligand, [{M’(tren)}3(?-tren)]6+ (M’ CuII ZnII). The crystal structures of three compounds show that atomic arrangement is formed by relatively isolated anionic cationic entities. irradiated blue l...

Prussian blue (PB) is a well-known archetype of mixed valency systems. In magnetic PB analogues {CxAy[B(CN)6]z}.nH2O (C alkali cation, A and B transition metal ions) and other metallic cyanometallates {Cx(AL)y[B(CN)8]z}.nH2O (L ligand), the presence of two valency states in the solid (either A-B, or A-A' or B-B') is crucial to get original magnetic properties: tunable high Curie temperature mag...
