The synthesis and structural characterization of [ReCl2(PPh3)2(NNHCOPh)(NHNHCOPh)]·1/2Et2O, a complex exhibiting linear hydrazido(2–) ligation and end-on hydrazido(1–) ligation

Abstract

The title ocmpound was prepared by treating [ReCl₂(PPh₃)₂(NNCOPh)] with excess of benzoylhydrazine in methanol Solution: X-ray crystallography reveals a unique example of monohapto-co-ordination by a hydrazido(1–) grouping, –NHNHR, and an unusual instance of mixed hydrazido(2–) and hydrazido(1–) co-ordination to a metal site.
