Bi- and tridentate coordination behaviour of a novel bis(phosphinimino)methanide ligand.

Herein, we report the synthesis of a novel ferrocenyl-functionalized bis(phosphinimino)methane ligand (CH (PPh NFc) ). Deprotonation of CH (PPh NFc) with KN(SiMe ) gave the dimeric species [K{CH(PPh NFc) }] , which was further reacted with ECl (E=Ge, Sn) to yield the tetrylene compounds [{CH(PPh NFc) }ECl]. The ligand and the resulting tetrylenes were examined for their electrochemical properties with the aid of cyclic voltammetry.
