Study of the Chemistry of Coordination of Oxide-anions of Nitrogen with Species of Iron and Copper as Models of Enzymes of the Cycle of the Nitrogen

Description

In the present work, a study is carried out about the reactivity of some nitrogen oxide-anions, like nitrite (NO2-) and trioxide-dinitrate (N2O32-), besides nitric oxide (NO), with copper species, iron, and cobalt in their states of oxidation II, in presence of the binding spectator bispicen. The synthesis and characterization of the [Cu(bispicen)NO2]BF4 was obtained, which can help to consolidate some mechanisms, proposed for the action of the nitrite reductase. The Fe(bispicen)(NO2)2 was also characterized; this is the fourth compound that presents two nitrites coordinated to an iron (II) through nitrogen. It has the characteristic of possessing short connection distances, which gives it a special attractiveness, and it opens the possibility of studying a spin exchange

Ademas se caracterizo el Fe(bispicen)(NO2)2 este es el cuarto compuesto que presenta dos nitritos coordinados a un hierro(II) a traves del nitrogeno. Tiene la caracteristica de poseer distancias de enlace cortas lo que le brinda un atractivo especial y abre la posibilidad del estudio de un intercambio de espin
