- Description
- The methylhydrazine complex [Ru(NH₂NHMe)(PyP)₂]Cl(BPh₄) (PyP = 1-[2-(diphenylphosphino)ethyl]pyrazole) was synthesised by addition of methylhydrazine to the bimetallic complex [Ru(µ-Cl)(PyP)₂]₂(BPh₄)₂. The methylhydrazine ligand of the ruthenium complex has two different binding modes: side-on (η²-) when the complex is in the solid state and end-on (η¹-) when the complex is in solution. The solid-state structure of [Ru(PyP)₂₋(NH₂NHMe)]Cl(BPh₄) was determined by X-ray crystallography. 2D NMR spectroscopic experiments with ¹⁵N at natural abundance confirmed that in solution the methylhydrazine is bound to the metal centre by only the -NH₂ group and the ruthenium complex retains an octahedral conformation. Hydrazine complexes [RuCl(PyP)₂(η¹-NH₂NRR´)]OSO₂CF₃ (in which R = H, R´ = Ph, R = R´ = Me and NRR´ = NC₅H₁₀) were formed in situ by the addition of phenylhydrazine, 1,1-dimethylhydrazine and N-aminopiperidine, respectively, to a solution of the bimetallic complex [Ru(µ-Cl)(PyP)₂]₂-(OSO₂CF₃)₂ in dichloromethane. These substituted hydrazine complexes of ruthenium were shown to exist in an equilibrium mixture with the bimetallic starting material.
