Resum:
At the present doctoral thesis present the basic molecular magnetism of compounds of coordination based at one binding *di-*anionico: (*L-2 = 4- (1,2,4-*triazole-4-*il) *etanosulfonato). In particular, we studied the phenomenon of transition of spin of a trimer of iron (*II) *poli-*aniònic at distinct scales, since a macroscopic scale ('*bulk') until molecular levels, ending with the deposition at surface. On the one hand, the behaviour *SCO 'macroscopic' modulated capsizing the packaging of glass and the connectivity among the trimers with a strategy of exchange *catiònic. On the other hand, we have found *bi-stability at systems highly diluted of the trimer of Faith (*II), at a solid mixed solution and at dissolution, where the forces of cooperation among trimers have reduced until molecular levels. This result warms us at studying the deposition and the behaviour of the trimer at several surfaces with a view to a first approach to a real app. Finally, we have fashioned a film *nanomètrica of the compound on silica, with properties of transition of intact spin. Besides, also we could further the process of miniaturisation further of the size *nanomètrica at growing a *subcapa ordered of the complex at a surface of gold through a deposition of tall void.
