摘要
The iminophosphorane Ph2P(CH2Py)(NSiMe3) (Py = NC5H4) is deprotonated at the C.-position in a reaction with [M{N(SiMe3)(2)}(2)] (M = Fe2+, Zn2+) to give metallaspirocycles in which the metal cations are N,N-chelated by the ring- and imino-nitrogen atoms of both monoanionic ligands. The molecular structures of [M{Ph2P(CHPy)(NSiMe3)}(2)] [M = Fe (1), Zn (2)] are discussed and general trends in the bonding of the [Ph2P(CHPy)(NSiMe3)](-) anion on metal coordination are deduced.
