  La hidrazona organometálica dinuclear [(h 5-Cp)Fe(h 6-p-MeO-C6H4)-NHN=CH-(h 5-C5H4)Fe(h 5-Cp)]+PF6- es preparada estereoquímicamente como su isómero trans por reacción de la hidracina organometálica precursora [(h 5-Cp)Fe(h 6-p-MeO-C6H4)-NHNH2)]+PF6- con ferrocencarboxaldehido. Se ha determinado su estructura cristalina y molecular que consiste en dos sanwiches de hierro(II) del tipo [(h 5-Cp)Fe(h 6-areno)]+ y [(h 5-C5H4)Fe(h 5-Cp)] en posición anti uno respecto del otro, los que se encuentran enlazados por un espaciador hidrazónico en forma de zig-zag

  The dinuclear organometallic hydrazone [(h 5-Cp)Fe(h 6-p-MeO-C6H4)-NHN=CH-(h 5-C5H4)Fe(h 5-Cp)]+PF6- (Cp=C5H5) is stereoselectively prepared as its trans isomer by reacting the organometallic hydrazine precursor [(h 5-Cp)Fe(h 6-p-MeO-C6H4)-NHNH2)]+PF6- with the ferrocenecarboxaldehyde. Its crystalline and molecular structure has been determined and consists of two iron(II) sandwiches of the type [(h 5-Cp)Fe(h 6-arene)]+ and [(h 5-C5H4)Fe(h 5-Cp)], in anti position one with respect to the other, and linked by a zigzag hydrazonic spacer
