The reaction of [(THF)Li{Ph2PC(H)Py}] with ZnCl2 in the presence of ZnO yields the zinc complex [Zn3{Ph 2PC(H)-Py}4O] (1). Deprotonation of the phosphane Ph 2P(CH2Py) with [Fe{N(SiMe3)2} 2] gives the iron complexes [{Ph2P(CH2Py)} Fe{Ph2PC(H)Py}2] (2) and [Fe{Ph2PC(H)Py} {N(SiMe3)2}]2 (3), depending on the ratio of phosphane. The solid state structures of the metal complexes illustrate the coordination flexibility of the [Ph2C(H)Py]--anion. Depending on the electronic requirements of the coordinated metal the anion acts as a (P,N)-chelating amide or C-coordinating carbanion with the P- and N-heteroatoms as donor bases.
