Magnetic properties, high-spin molecules

Zelentsov et al. also observed that the high spin fraction in virtually all samples increased to varying extents after the samples were heated [105]. The origin of this effect is not clear since the complexes were mostly unsolvated and thus loss of solvate molecules, the most common cause of such a change, was not applicable. Nevertheless, the importance of the inclusion of lattice water molecules in co-determining the spin crossover properties is evident in the different magnetic properties of Li[Fe(5-Br-thsa)2] [105] and Li[Fe(5-Br-thsa)2]-H20 [111]. For the unsolvated compound neg= 1.93 B.M. 

Aryl nitrenes have been studied extensively over the last decades and are used in several industrial processes such as microlithography. Aryl nitrenes have also been used in photoaffinity labeling bioorganic molecules. The pursuit for organic magnetic material has sparked renewed interested in nitrene intermediates, which are ideal candidates for magnetic material because of their high spin properties. ...
