Electronic response of a (P,N)-based ligand on metal coordination†
Abstract
The reaction of [(THF)Li{Ph2PC(H)Py}] with ZnCl2 in the presence of ZnO yields the zinc complex [Zn3{Ph2PC(H)Py}4O] (1). Deprotonation of the phosphane Ph2P(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
