Abstract

The reaction of the potentially tetradentate N ₄-donor ligand N,N′-bis[(2-aminophenyl)methylidene]ethane-1,2-diamine (H₂ane) with various rhenium(V) precursors led to the formation of different rhenium(V) complexes. With trans-[ReOBr₃(PPh₃)₂], the unusual ‘3+3’ complex cation [Re(tnn)(Htnn)]²⁺ (H₂tnn = N-(2-aminophenylmethylidene)ethane-1,2-diamine) was isolated. With trans-[ReO₂(py)₄]Cl, the complex [ReO(dne)] was found (H₃dne = N ¹-2-aminobenzyl-N ²-2-aminobenzylideneethane-1,2-diamine), and the cationic complex [ReO(ane)]⁺ was formed from cis-[ReO₂I(PPh₃)₂]. These products were characterized by ¹H NMR and IR spectroscopy, and by X-ray diffraction.
