FIRST X-RAY CRYSTAL STRUCTURE OF A BIMETALLIC COMPLEX CONTAINING A p -COORDINATED HYDRAZONE: [(h 5-Cp)Fe(h 6-p-MeOC6H4)-NHN=CH-(h 5-C5H4)Fe(h 5-Cp)]+PF6
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 crystalli...

| Sumario: | 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 |
