Abstract

Using trans-[NH₂Me₂][Ru(η²-ox)₂(H₂O)₂]·4H₂O 1 as starting material, as well as its original preparation as a guide, the synthesis of trans-[NH₂Me₂][Ru(η²-ox)₂(PPh₃)₂] 2, trans-[pyH][Ru(η²-ox)₂(H₂O)₂]·4H₂O 3, trans-[pyH][Ru(η²-ox)₂(py)₂]·2·.5H₂O 4, [Ru(η²-ox)(py)₄]·4CHCl₃ 5 and fac-[Ru(η²-ox)(DMSO-S)₃(DMSO-O)]·1.34H₂O 6 are outlined. Complexes 2–6 have been characterized using elemental analysis, IR, UV-visible, ¹H NMR, and X-ray diffraction. In addition, their electrochemical behaviour has been analyzed using cyclic and Osteryoung square-wave voltammetries with complex 6 displaying linkage isomerization.
