Abstract
This report demonstrates a simple procedure for the preparation of three Ru(II) hydrazine and hydrazone complexes formulated as [Ru(NH2NH2)2L4][BPh4]2 (L = ethyldiphenylphosphine (3), and [Ru(NH2:CMe2)2L4][BPh4]2 (L = methyldiphenylarsine (4), L = ethyldiphenylphosphine (5). The complexes were characterized by IR, elemental analysis and 1H NMR spectroscopy. All the three complexes show N−N absorption in the range between 1031 – 1029 cm-1 indicating the presence of coordinated hydrazine. Evidence of ethyldiphenylphosphine coordination to the Ru(II) centre was further established by 31P NMR spectroscopic analysis of 3. The obtained complexes could have potential applications in other fields such as catalysis and synthesis of nanomaterials.
