 Abstract    While the reaction of anhydrous iron(III) chloride with the chelate ligand [(C6H5)2P(0)]2NH (6) is an efficient way to synthesize the new tricyclic compound imido-tetraphenyl-diphosphinato-0,0'iron(III), [Fe{0-P(Ph2)=N-P(Ph2)= 0 }3] (4), treatment of [(C6H5)2P]2NLi (1) with anhydrous iron(III) fluoride in THF represents a simple route to obtain the phosphorus-phosphorus connected species Ph2P-N=PPh2-PPh2=N-PPh2(7). Both compounds were charac­ terized by X-ray crystallography, 'H ,31 P {1H}, 13C {1H} NMR, IR, Raman and mass spectra.

 Title    Chemie polyfunktioneller Moleküle, 127 [1] PPh2-Eliminierung aus dem PP-verknüpften Phosphazen Ph2P-N=PPh2-PPh2=N-PPh2 mit [C5H5Fe(CO)(/x-CO)]2; Kristallstrukturanalyse des Phosphazen-Derivats Chemistry of Polyfunctional Molecules, 127 [1] PPh2 Elimination from the PP Connected Phosphazene Ph2P-N=PPh2-PPh2=N-PPh-, with [C5H5Fe(CO)(^-CO)]2; Crystal Structure of the Phosphazene Derivative  
 Abstract    The reaction of Ph2P-N=PPh2-PPh2=N-PPh2 (Ph = C6H5, 2) with [CpFe(CO)(^-CO)]2 (Cp = C5H5, 3) yields under elimination of a PPh2-group from 2 and cleavage of the Fe-Fe bond in 3 the monocyclic ferraphosphazene complex Cp(OC)Fe-Ph2P-N=PPh2=N-PPh2 (4) and Ph2P-PPh2 (5). In a side reaction the P-P bond of 2 is also cleaved in a redox process to give Cp(OC)Fe-Ph2P-N-PPh2 (7). Compound 4 has been characterized by a crystal structure determination.
